Delta y or Δy means the change in vertical displacement.
It is normaly used in equations related to dropped or launched objects.
To determine the units of the y-intercept in a linear equation, you need to look at the units of the y-axis. The y-intercept represents the value of y when x is zero, so the units of the y-intercept will be the same as the units on the y-axis.
The sine wave equation is y A sin(Bx C), where A is the amplitude, B is the frequency, and C is the phase shift. It is used to represent periodic oscillations in fields like physics, engineering, and music by showing how a wave varies over time. The equation helps to visualize and analyze the behavior of oscillating phenomena, such as sound waves, electrical signals, and mechanical vibrations.
The equation for a sine wave is y A sin(Bx C) where A is the amplitude, B is the frequency, and C is the phase shift.
The equation for y(x, t) in terms of the amplitude a, angular frequency k, and the variables x and t is y(x, t) acos(kx - t).
The equations for projectile motion are: Horizontal motion equation: x = v₀x * t Vertical motion equation: y = v₀y * t - 0.5 * g * t^2 Final velocity in the y-direction: v_yf = v₀y - g * t Where: x and y are the horizontal and vertical positions respectively v₀x and v₀y are the initial velocities in the x and y directions respectively g is the acceleration due to gravity t is the time elapsed
It means a change in. For example if you had Delta(y) that would mean a change in Y values in respect to another variable
If you mean the slope of the line with equation y = x then it is 1 and there is no y intercept
y-x is an expression, not an equation. Therefore, the question does not make sense.
That pyramid symbol (or better defined as a triangle as to not get confused with lower mathematics / geometry) simply means a change in something. The actual term is "delta" and it is also known as the derivative of y as seen here: (delta) y / (delta) x. (delta) y / (delta) x would be read as the change in y with respect to x.
If you mean: y = x+4 then the perpendicular equation can be y = -0.5x+4
Equivalent equation means two equations, x and y,such thatx = y
Do you mean y = 4x+9? If so then the y intercept is 9
If you mean y = 2x then it is a straight line equation
If you mean: y = -4x+3 then the parallel equation will have the same slope but a different y intercept
If you mean: (-4, 8) and (0, 0) then the equation works out as: y = -2x and there is no y intercept
When an equation is in slope-intercept form (y = mx + b), the slope is the variable m, where y is the the y-coordinate, x is the x-coordinate, and b is the y-intercept (where the line crosses the vertical axis). Slope is calculated as rise over run, or delta y over delta x. For example, you have a line on a graph and you need to know the slope. Find two points from that line and write down its coordinates--say, (2,6) and (4,8). The change in y (delta y, rise) is 2, because 8 - 6=2. The change in x (delta x, run) is 2, because 4 - 2=2. Note: make sure that when subtracting the x and y coordinates, that you do them in order. For example, don't go 8-6 and then 2-4. Since slope is delta y over delta x, the slope of the line is 2/2, or 1.
If you mean 28 = 7+y then the solution of the equation is y = 21
