Answer:
x = - 3
Step-by-step explanation:
Since the x- coordinates of both points are equal, both - 3
This indicates the line is vertical with equation
x = c ( c is the value of the x- coordinates the line passes through )
The line passes through (- 3, 9) and (- 3, - 5) with x- coordinates - 3 , then
x = - 3 ← equation of line
