SOLUTION: what is the y-intercept of the graph of 9+x/2= -5+5?

Question 525943: what is the y-intercept of the graph of 9+x/2= -5+5?
Answer by oberobic(2304) (Show Source): You can put this solution on YOUR website!
9 + x/2 = -5+5
9 + x/2 = 0
x/2 = -9
x = -18
Regardless of the value of 'y', x = -18.
The means the slope would have a value for y-y₁ divided by 0, which is undefined.
So, x = -18 is a vertical line crossing the x-axis as (-18,0).
There is no y-intercept because x never = 0.
