The y-intercept equals 0.
by just doing the problem
Slope and y-intercept of y equals 2.5x is: Slope is 2.5 and y-intercept is 0
By including the + or - signs in the question
What is the slope-intercept form of 7x-3y equals 4
the x intercept is 3
Slope is zero y-intercept is -7 there is no x-intercept for this equation
x-intercept = -21y-intercept = 168
