well, just check all the choices against the equations. For #1,
y < 2 - 2x
y > 2x -3
(4, 0)
0 < 2 - 8? No
(0, 0)
0 < 2 - 0? yes
0 > 0 - 3? yes
(3, 4)
4 < 2 - 6? No
do the others in like wise.
Which of the following ordered pairs is included in the solution set of the system, y < 2 - 2x and y > 2x -3?
(4, 0)
(0, 0)
No Solution
(3, 4)
2. Choose all correct answers. Which of the following are solutions of the system?
x < 3 and x + y < 5
(2, 2)
(4, 2)
(2, -1)
(-1, 0)
3. Which one of the following is a solution of the system?
y <-1 and y > 8
(6, 9)
No Solution
(-2, 4)
(0, 0)
4. Which ordered pair does not satisfy the system 2x + y > 0 and -2x - y > -8?
(-1, 4)
(-1, -1)
(3, -2)
(2, 3)
