<span>Choices were: A.5  B.7  C.12  D.15</span>

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.
