The y-intercept (where x = 0) of the equation is at -20.
For every 60 the x runs, the y falls by -10. Use rise over run to determine the slope of the equation.

Slope-intercept form is determined by the following equation:

m is your slope, and b is your y-intercept.
Plug the slope and y-intercept into the equation.
