Question 100562
Yes, it is correct.
.
Any time you get a division by zero for the slope, it tells you that the slope is undefined, and
that means that the graph is a vertical line.  If you look at the two points that are given,
you will notice that both points have -2 as their x value. If you plot the two points,
one of them (-2, -5) is directly under the other point (-2, 4). When you connect these two
points with a line, you will see that the line is vertical.
.
Hope this helps you to interpret the problem and what is means to have a slope that involves
dividing by zero.
