Question

Given the equation y = mx + b, which variable represents the slope of the line?

Answer 1

Answer:

Variable "m"

Step-by-step 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.
