Hey there! :)
Answer:
y -3 = -2(x + 4).
Step-by-step explanation:
Begin by calculating the slope of the line shown in the graph. Use the slope formula:

Plug in two coordinates:

Simplify:


Therefore, the slope of the line is 1/2.
A line that is perpendicular contains a slope that is the negative reciprocal. Therefore:
1/2 --> -2.
Plug the slope into the point-slope formula:
y -3 = -2(x + 4). This is your equation in point-slope form!
