Question

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

y < −3x + 3
y < x + 2

(1, −5)
(1, 5)
(5, 1)
(−1, 5)

Answer 1

the answer is (1,-5)

Explanation:

plug in the x and y values and see if they are true

y<-3x+3

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

-5<-3+3

-5<0 is true

y<x+2

(-5)<(1)+2

-5<1+2

-5< 3 is true also

Answer 2

(1, −5)

Explanation:

Because in this case it is less than and the -3x would be cancelled out and I had this question and that correct answer was A(1,-5).

Hope this helps:)
