PLSSSSS HELP!!!!!

Write the equation of a line that is perpendicular to the given line and that passes through the given point.
y- 4 = (x+3); (-7,8)

O A. y-8 = -2/5(x-7)
OB. y-8 = -2/5(–7)
O C. y-8 = -2/5(x + 7)
O D.y-8 = -2/5(x +7)

The correct answer is C.
First plug in (-7,8) and see that it only satisfies C and D.
The slope of the original line is 5/2, which has a positive slope. The perpendicular line must have a negative slope, so between C and D the correct answer is C
