Use an equation to find the value of k so that the line passing through (−4,k) and (6,−7) has a slope of −15.

k = 143

Step-by-step explanation:

Using the slope formula

(k- -7)/(-4-6) =-15

(k+7)/(-10) = -15

k+7 =-15*-10

k+7 = 150

Subtract 7

k+7-7 = 150-7

k = 143

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.
