Question

11) Find x if the line through (-2, 4) and (x, 6) has a slope of 2/9?

Answer 1

Answer: x = 7.

Step-by-step explanation:

The formula for a slope is y₂ - y₁ / x₂ - x₁.

Plug in the values into the formula.

`(6 - 4)/(x + 2)`

`(2)/(x + 2)`

The slope is 2/9, so x + 2 = 9.

Hence, x = 7.
