Write the equations of three distinct lines that have the same y-intercept,-1.

Three possible answers are:

y = 2x-1

y = 5x-1

y = - 3x-1

All of them have the same y intercept of - 1. The slopes are the only thing that differ.

Any linear equation can be written in the form y = mx+b where

m = slope

b = y intercept
