The slope is defined as %28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29%29
Since both x coordinates are the same, the denominator of the slope is 0.
A fraction with 0 in the denominator is undefined.
These two points are on the vertical line that goes through (-4,0)
The equation of that line is x+=+-4
