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

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

Answer 2

the first one is
-5<-3+1=-5<-2= correct
the second one is
5<-3(1)+3
5<-3+3
5<0
the thrid one is
1<-15+3=1<-12
and the last one is 5<3+3=5<6

so the first and last one are correct.

Answer 3

then tou must do it for the second equation
-5<1+2=-5<3= correct
and
5<-1+2=5<-1= incorrect

Answer 4

so the answer is number 1

Answer 5

or (1,-5)
