Question

On a coordinate plane, line M N goes through points (2, 3) and (negative 3, 2). Point K is at (3, negative 3).

Which point could be on the line that is perpendicular to Line M N and passes through point K?

(0, −12)
(2, 2)
(4, 8)
(5, 13)

Answer 1

suitable is (4, 8)

Explanation:

slope of MN (y2-y1)/(x2-x1) = (2-3)/(-3-2)= -1/-5 = 1/5

line MN and line K is perpendicular

(1/5)*(m2) = -1

slope of k which is m2 is -5

slope of K (y2-y1)/(x2-x1)= 5

slope of MN (-3-y1)/(3-x1)=5

suitable is (4, 8)

Answer 2

2,2 is correct
