Answer:
x=-9
Step-by-step explanation:
M(slope)=y2-y1/x2-x1
m=-5-5/-9+9
m= -10/0
This means the slope is undefined. Whenever the slope is undefined, the line is vertical and is passing through the x-axis and parallel to the y-axis. Take the given coordinate (-9,5) and all you do is put x= -9. That's the equation of the line.
