Answer
Straight line parallel to Y axis which is cutting X axis at only one point(-7,0).
Work Step by Step
Here I am using the result that m(slope of the graph) = $\frac{\Delta y}{\Delta x}$
We use the coordinates of the given points to find the slope:
$m=\frac{5-2}{-7-(-7)}=\frac{3}{0}$
So, the slope is not defined.
Thus, the graph is a straight line parallel to the $y$-axis which is cutting the $x$-axis at the point $(-7,0)$.
