Question

1. Which ordered pair makes the equation true?

4x – 9y = –5

(Points : 1)
(–5, –2)
(–1, 1)
(10, 5)
(20, 4)

Answer 1

For each pair the first is the x value, and the second is the y value

take the x value and multiply by (=4x) (BE CAREFUL OF THE SIGN +/-)
take the y value and multiply by 9 (=9y) (BE CAREFUL OF THE SIGN +/-)

Subtract the second number from the first (=4x-9y) (BE CAREFUL OF THE SIGN +/-)


That is th answer fro that pair. IF it is equal to -5 then that is th ecorrect answer . If not - try another pair.

(BE CAREFUL OF THE SIGN +/-)
