Question

Find the slope: -3x + 7y = 21​

Answer 1

3/7

Explanation:

First, separate the y from the rest of the equation by adding 3x to both sides of the equation to get

7y=3x+21.

then, divide all terms by 7 to get the y alone.

y=(3/7)x+3

The value in front of the x is now the slope. So the slope is 3/7.
