Question 142661: Find the slope if it exsists. m=? Help me with this? The slope is -5?
x = -5

You can put this solution on YOUR website!
If you plot x=-5, you get a vertical line where every point on that line has an x coordinate of -5.
Slope = delta y / delta x.
delta x would always be -5+-+%28-5%29+=+0
But you know that a fraction with a zero denominator is undefined. So the slope is undefined for any vertical line.
