Question

Which is a solution to the system of
inequalities y < 2 - 4x and 6y - 9x > 15?

F. (-2, 1) H. (0, 5)
G. (-1, -3) I. (2, 4)

Answer 1

Plug them back into the inequalities and see which (x,y) is true for both inequalities.

Answer 2

so plug the first equation into the second equation?

Answer 3

y < 2 - 4x and 6y - 9x > 15

When (-2, 1)

y < 2 - 4x
1 < 2 - 4(-2)
1 < 2 + 8
1 < 10
TRUE

6y - 9x > 15
6(1) - 9(-2) > 15
6 + 18 > 15
24 > 15
TRUE

Answer 4

so do you do that for all of the choices?
