Find the equation of the line through point (4,−1) and perpendicular to y=x+2. Use a forward slash (i. e. "/") for fractions (e. g. 1/2 for 12).

Perpendicular = opposite sign and reciprocal slope
Y = x + 2 (has slope is 1)
-1/1 = -1
Y = -1x + b
Plug in the point
-1 = -1(4) + b
-1 = -4 + b, b = 3
Solution: y = -x + 3

Ithink the answer is d. not sure but don’t answer it.
