Wasn’t there for class so I don’t really know how to do this someone help :(

Step-by-step explanation:

Substitute (x, y) value in 5x -  4y and if you get 17 then (x , y) is the solution.

If you are getting 17, then (x, y) is not a solution.

1) (1 , -3)

5x - 4y = 5*1 - 4*(-3)

            = 5 + 12

            = 17

(1, - 3) is a solution.

2) (-6, 2)

5x - 4y = 5*(-6) - 4*2

           = -30 - 8

          = -38   ≠ 17

So, (-6 , 2) is not a solution.

3) (-3 , -8)

5x - 4y = 5*(-3) - 4* (-8)

           = -15 + 32

           = 17

So, (-3 , -8) is a solution.

4) (2 , 9)

5x - 4y = 5*2 - 4 *9

           = 10 - 36

           =  -16 ≠ 17

So, (2 , 9) is not a solution

this doesn't make sense lol

i can answer this question sweetie!
