Hello!

You put the values in for x and y

(x, y)
------------------------------------------------------------------------------------------------------
(-9, -12)

4(-9) + 5(-12) = 24

Combine like terms

-36 - -60 = 24

Since they equal 24 it is the first one
------------------------------------------------------------------------------------------------------
(1, -4)

4(1) - 5(-4) = 24

4 - -20 = 24

Since they equal 24 it is also the second one
------------------------------------------------------------------------------------------------------
(6,0)

4(6) - 5(0) = 24

24 - 0 = 24

Since they equal 24 it is also the third one
------------------------------------------------------------------------------------------------------
4(4) - 5(8) = 24

16 - 40 = 24

Since they do not equal 24 it is not the last one
------------------------------------------------------------------------------------------------------
The answers are (-9, -12), (1, -4) and (6,0)

Hope this helps!
