Question

Find the missing value so that the line passing through the points (7, 1) and (x, 4) have the slope of 3/4 *

Answer 1

11

Explanation:

`(3)/(4) = (4 - 1)/(x - 7) \\ \\ (\cancel 3)/(4) = (\cancel 3)/(x - 7) \\ \\ (1)/(4) = (1)/(x - 7) \\ \\ 4 = x - 7 \\ \\ 4 + 7 = x \\ \\ 11 = x \\ \\ x = 11`
