What is the relationship between the variables y and x when graphed on a coordinate plane?
In a graph, the relationship between the variables y and x can be shown by how they are connected by a line or curve. This relationship can be linear, meaning a straight line, or nonlinear, meaning a curve. The slope of the line or the shape of the curve indicates how the variables change in relation to each other.

Is ammonia a polar covalent bond?
Yes, ammonia (NH3) has a polar covalent bond between the nitrogen and hydrogen atoms. This is because nitrogen is more electronegative than hydrogen, leading to an uneven distribution of electrons in the molecule.
What is the dependent and independent variable when you measure the absorption of heat by color?
For dependent and independent variable, remember DRY MIX:D - dependent variableR - response you are recording in your notebookY - graphed on the Y-axisM - the thing manipulated by the scientistI - independent variableX - graphed on the X-axisSo for absorption of hear by color:the dependent variable is the absorption of heat: that's the response you are recording and when you graph it, this value goes on the Y-axis.the independent variable is the color: that's the thing you manipulated and when you graph it, this value goes on the X-axis.
Is ammonia is a polar covalent bond?
Yes, it is a polar covalent bond because there is only on Nitrogen atom and three hydrogen atoms, therefore making it uneven or unequal. It can be graphed in a pyramid shape. A polar covalent bond is is a covalent bond in which the electrons are shared unequally, therefore giving evidence.
What are coefficients and subscripts?
Coefficients are the numbers attached to variables in algebraic equations. If there is no number attached to the variable it is an understood 1. These numbers are multiplied with the variables. When you solve for the variable and put that value back into the algebraic equation in place of the variable it must make the equation true. Subscripts are numbers that are written at the bottom right of a value (variable/ number). They look similar to exponents except they are below the value. They are used as identification so you can distinguish where the value came from. Having them below the value keeps the subscripts from getting mixed up with exponents. For example when you are talking about finding the slope of a line you first choose 2 points. Points are labeled by an ordered set of numbers that specify the exact location of the point. Lines are graphed in 2-dimensions so there are 2 numbers used to identify the point. the first number refers to the horizontal placement of the point from the origin of the graph (the point where the 2 axes intersect) and the second number refers to the vertical placement of the point. We write the ordered numbers in parentheses ex (2, 3) would mean the point is 2 units to the right of the origin and 3 units up from the origin. In algebra we refer to the coordinates (ordered numbers) of a point as (x, y). When we talk about finding the slope of a line we find the ratio of: the difference (subtraction) of the y-values to the difference of the x-values. When writing and using formulas it is necessary to keep track of where the variables came from. For slope we are using 2 points so we have to keep track of which x- and y-value belong to the 1st point and which ones belong to the 2nd point. This is where subscripts come into use. They help identify where the variables came from and will not be confused with exponents
How is he melting curve of duplex DNA affected by adding a small amount of ethanol?
If a DNA strand is denatured, it is generally as a result of an increase in temperature. If monitored, the absorbance can be graphed as a function of temperature. The midpoint in the resulting curve is the melting point. The melting curve can be altered by decreasing the ionic concentration, causing an decrease in the melting temperature. This is due to the Poly-anion nature of the DNA helix. When the ionic strength is decreased, the stability of the DNA strand decreases. When a small amount of ethanol is added, the non-polar effect has the biggest impact. When EtOH is added, the non-polar nature of the solution is decreased, resulting in a decreased importance of the hydrophobic forces on the stability of the helix, resulting in a lower melting temperature.

In the equation ykx k is the constant of what?
In the equation ( y = kx ), the constant ( k ) represents the proportionality constant that relates the variables ( y ) and ( x ). This means that for every unit increase in ( x ), ( y ) will change by ( k ) units, indicating a direct linear relationship between the two variables. The value of ( k ) determines the slope of the line when graphed on a coordinate plane.
A definition of a solution to a system of equations?
A system of equations is a set of two or more equations with the same variables, graphed in the same coordinate plane
When a relationship is graphed ona cartesian coordinate system what value is usually measured by the vertical axis?
It is f(x), y or the "output".
What is the definition of a linear equation?
A linear equation is a mathematical expression that represents a straight line when graphed on a coordinate plane. It typically takes the form ( ax + by = c ), where ( a ), ( b ), and ( c ) are constants, and ( x ) and ( y ) are variables. The equation describes a relationship between the variables that can be solved for one variable in terms of the other. Linear equations have a degree of one, meaning the highest power of the variable is one.
When a relationship is graphed on a Cartesian coordinate system what represents the dependent variable?
In the Cartesian plane, the dependent variable is usually plotted on the y-axis.
What is always graphed on the Y-axis?

A coordinate plain
What is the cartesian coordinate plane?
That's the name of the plane with the horizontal x-axis and the vertical y-axis on which equations and inequalities with two variables are graphed. The Cartesian coordinate plane is to two dimensions as the number line is to one dimension.
