What is the value of k is m= -3 and the line passes theough points (1,-3) and (-5,k)

k=15

Step-by-step explanation:

slope (m) is (y₂-y₁)/(x₂-x₁)

so if we plug in the points, we can solve for k

(k-(-3))/(-5-1) = -3

(k+3)/(-6) = -3, multiply both sides by -6

k+3 = 18, subtract 3 from both sides

k=15
