Which equation represents the line passing through the points (3, 2) and (−9, 6)?

x − 3y = 9

x + 3y = 9

3x − y = −9

3x + y = 9

Question

Which equation represents the line passing through the points (3, 2) and (−9, 6)?

 x − 3y = 9

 x + 3y = 9

 3x − y = −9

 3x + y = 9

jim_thompson5910 · Answer

Since you're given the answers, you can check them

x − 3y = 9

3 − 3(2) = 9 ... plug in x = 3 and y = 2 (from the point (3,2))

3 - 6 = 9

-3 = 9

which is false

So (3,2) does NOT lie on the line x-3y = 9
