Question

The points (2,-5) and (5,r) lie on a line with slope 2. Find the missing coordinate r.

Answer 1

Answer: r = 1

Explanation:

The slope of a line can be represented as
`(y_2-y_1)/(x_2-x_1)`. Plugging in the following values would provide you with:

`((r)-(-5))/((5)-(2)) =2`

`(r + 5)/(3) = 2`

`r + 5 = 6`

`r = 1`

Hope it helps :) and let me know if you want me to elaborate on anything.
