Question

How do you find the slope given -2x-7y=21?

Answer 1

`-2/7`

Explanation:

Given equation of straight line: `-2x-7y=21`

`y=-2/7x-3`

Comparing above equation with the slope-intercept standard form of straight line: `y=mx+c` we get

`m=-2/7` & `c=-3`

hence, the slope of given line is `m=-2/7`
