Choices were: A. 5 B. 7 C. 12 D. 15

k (x, 9) = (-10,-6)

k*x = - 10

k*9 = - 6 Distributive property of multiplication

k*9 = - 6

k = - 6/9

k = - 2/3 Get the value of k to solve for the value of x.

k*x = - 10

-2/3 * x = - 10

x = - 10 : - 2/3

x = - 10 * - 3/2

x = (-10 * - 3) / 2

x = 30/2

x = 15 Choice D.
