If you mean the gradient then it would be -3/2 because if you multiply the 2 together they equal minus 1. That’s how u figure out if 2 lines are perpendicular
Midpoint-L(0,5) ONLY (0,7)
0,5+0,3
Add the average!
(-2,3)=extra info N(4,1)
<15,3> x k (6,5)

Multiply it by 12
Then you have your answer
Subtract (1/3)x from both sides of the equation.
(1/3)(x) - (1/3)(x) + y = -(1/3)(x) + 4
0 + y = -(1/3)(x) + 4
y = -(1/3)(x) + 4
Done!
The answer is C There your answer
