Question

Which of the following points lie in the solution set to the following system of inequalities?

y < -3x + 3
y < x + 2

Answer 1

(1, -5)

(1, 5)

(5, 1)

(-1, 5)

Answer 2

As I said earlier, plug in these set into the inequations to find which one satisfies both inequalities.

Answer 3

If you substitute the values into the inequalities they should be right

1. (1, -5)
-5 < -3(1) + 3
-5 < -3 + 3
-5 < 0

-5 <(1)+2
-5 < 3

2.(1,5)
5 <-3(1) + 3
5 < -3 +3
5 < 0

and so on....

Answer 4

substitute the values and verify or analyse from the graphs......
