Question

Find the missing value so that the ordered pair have the given slope. (x,-1) and (-2,-3);m=-(1)/(2)

Answer 1

x = -6

Explanation:

Points: (x, -1) and (-2, -3).

x_1 = x; y_1 = -1; x_2 = -2; y_2 = -3

slope = (y_2 - y_1)/(x_2 - x_1)

-1/2 = (-3 - (-1))/(-2 - x)

Cross multiply.

(-2 - x)(-1) = (-2)(2)

2 + x = -4

x = -6
