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