Question

The points (4,1) and (x, -6) lie on the same line. If the slope of the line is 1, what is the value of x? A. X = -3 B. X = 3 C. X = 9 D. X = 11

Answer 1

Explanation:

Use the slope formula here along with the fact that the slope is equal to 1:

`1=(-6-1)/(x-4)` and

`1=(-7)/(x-4)` and cross multiply to get x - 4 = -7 so

x = -3
