Which of the following ordered pairs is included in the solution set of the system, y < 2 - 2x and y > 2x -3?
A. (0, 0)
B. (3, 4)
C. (4, 0)
D. No Solution

Answer 1

Isolate the constant:

y < 2 - 2x, becomes
y+2x < 2

y > 2x -3, becomes
y-2x > -3

we have
2 > y + 2x
-3> y - 2x

check which set is true.
(0, 0)
2 > y + 2x [true]
-3> y - 2x [false]

(3, 4)
2 > y + 2x [false]
-3> y - 2x

(4, 0)
2 > y + 2x [false]
-3> y - 2x

no set fits meets the requriments, thus, no solution

Answer 2

Thanks

Answer 3

no problem
does it make sense how to do these problems?
you get the constant to one side, then start plugging in the choices to see which is true
