Which of the following points lies on the line represented by 3 x + 7 y = 21 ?

Explanation:

I do not know the rest of the question (answer choices), however, what you want to do with this equation is put it into slope-intercept form to be able to test which points might lie on that line.

3x + 7y = 21

7y= -3x + 21

y= -3/7x + 3

Now, you want to plug in your values to see which set this equation satisfies.
