y = mx + b

Where:
m is the slope of the line.
b is the y-intercept of the line.

Explanation:

Consider y = x

graph{y=x [-10, 10, -5, 5]}

In this equation, the coefficient to x is 1 and our y-intercept is 0.

We could think of that equation as looking like:

y = 1x + 0

Notice that the graphed line has a "rise-over-run" of 1/1 which is just 1 and the line passing through the y-axis at y=0
