Answer 1

where is the second equation ?

Answer 2

That is all

Answer 3

oh ok, then simply plugin each point and see which one satisfies

Answer 4

Okay

Answer 5

lets see if first option satisfies

A. (2, -4)

5x - 2y = -9

plugin x = 2, y = -4 :

4(2) - 2(-4) = -9

8 + 8 = -9
16 = -9

FALSE

Answer 6

so option A is not ur answer

Answer 7

similarly, test next option

Answer 8

B. (-1, 2)

5x - 2y = -9

plugin x = -1, y = 2

5(-1) -2(2) = -9

-5 - 4 = -9

-9 = -9

TRUE

Answer 9

so, option B is ur answer

Answer 10

see if that makes some sense
