#y = mx + b#

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

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#
