# What is the science equation from a straight line graph?

ax + by + cz + ... = k

where x, y, z, etc are variables

and a, b, c etc and k are constants.

In the simple case of 2 variables, this becomes

ax + by = k which can be rewritten as y = mx + c (different c from the first equation above).

### Are linear equations and functions the same?

No. A linear equation is just one type of function. If you graph a linear equation, you get a straight line. A "function" on the other hand can take on many different forms: a straight line, a wave line (the sine function), a parabola, etc. No. A linear equation is just one type of function. If you graph a linear equation, you get a straight line. A "function" on the other hand can take on…

### What type of graph yields to a straight line?

A linear graph. A graph with an equation of the form: a1x1 + a2x2 + ... + anxn + c = 0 where the ai are constants and xi are variable (i = 1,2, ... n) will be a straight line in n-dimensional space. In 2-dimensions, the equation is more commonly written as ax + by + c = 0. The key characteristic of the equation is that the variables appear as single terms, with…

### What is the difference between a line graph and a linear equation?

A linear equation, when plotted, must be a straight line. Such a restriction does not apply to a line graph. y = ax2 + bx +c, where a is non-zero gives a line graph in the shape of a parabola. It is a quadratic graph, not linear. Similarly, there are line graphs for other polynomials, power or exponential functions, logarithmic or trigonometric functions, or any combination of them.

### How do you graph line in slope intercept fom?

The "form" only refers to how the equation of the line is written. It has no effect on what the line looks like when the equation is graphed. To graph a linear equation, no matter what form it's written in: -- Pick a number for 'x'. Use the equation to calculate 'y'. Graph the point. -- Pick another 'x'. Use the equation to calculate the new 'y'. Graph the point. -- Draw a straight line…

### Can you show me a linear graph?

The link will show you several different kinds of graph. A straight line graph will literally be one straight line, representing a linear equation perhaps, or showing the closest straight line fit to a set of data. There are other line graphs that connect points on a grid with straight lines, even though the over-all graph may not be one single straight line. Graphs are very interesting and extremely useful. You can often find a…
