Question

Which point lies in the solution set for the following system of inequalities?

x − y > 3
x + 2y < 6

(7, 1)

(3, 4)

(−2, 2)

(4, −2)

Answer 1

Hint: Substitute the points into the equations and test to see which points are true for both.

Answer 2

ok i got (−2, 2)

Answer 3

what did u get

Answer 4

Okay, let me substitute (-2,2) for the first equation:

(-2) − (2) > 3
-2 - 2 > 3
-4 > 3

-4 is greater than 3? Really?

Answer 5

no lol im sorry

Answer 6

The points where x > y are more likely to work for this. So, start with those points.

Answer 7

i meant (3, 4)

Answer 8

For the point (3,4) is x > y ?
