Answer:

Variable "m"

Explanation:

Hello!

The equation
y = mx +b is perhaps the most used equation when representing a line. The parts of the equation:

  • y = output, y-value, ordinate...
  • m = slope, rate of growth, rise over run...
  • x = input, x-value, abscissa...
  • b = y-intercept

____________________________________________

Let's use an example: y = 2x + 5

We want to find the y-value when x is 2.

To solve, simply plug in 2 for x:

  • y = 2(2) + 5
  • y = 4 + 5
  • y = 9

So, the coordinate when x is 2 is (2,9), remember that coordinates are written in (x,y) format.
