You can put this solution on YOUR website! In the formula for an algebra equation (y=mx+b), what is the x-intercept and the y-intercept?
.
The y-intercept is easy -- by setting x = 0 we see that the y-intercept is at
(0,b)
.
For the x-intercept, set y=0 and solve for x
y=mx+b
0=mx+b
-b=mx
-b/m=x
So, the x-intercept is at:
(-b/m, 0)
