Question

12) If the slope between (3, x) and (5,9) is 1, what is
the value of x?

Answer 1

x + 7

Explanation:

Slope is the change in y over the change in x

`(9-x)/(5-3)` = 1

`(9-x )/(2)` = 1 Multiply both sides of the equation by 2

9 - x = 2 Subtract 9 from both sides

-x = -7 Multiply both sides by -1

x = 7
