Question

find the missing value so that the line passing through the points has the given slope (x,-4) and (2, 8); m=-3

Answer 1

Answer:

The missing x would be 6

Step-by-step explanation:

To find the missing value fo x, use the slope formula and solve for the missing variable.

m(slope) = (y2 - y1)/(x2 - x1)

-3 = (8 - -4)/(2 - x)

-3 = 12/(2 - x)

Now we cross multiply to solve.

12 = -3(2 - x)

12 = -6 + 3x

18 = 3x

6 = x
