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

Y<-3x +3 (x=-1)
Y< -3(-1) +3 = 3 + 3 = 6

Y< x+2 (x=5)
Y< 5+2=7

Answer 2

How's that?

Answer 3

1,-5. ?

Answer 4

If it's 1 and -5, then it would be different.

Y<-3(1) + 3= -3 +3= 0
Y<0

Y< -3(5) + 3
Y< -15 + 3= -12
Y<-12

Of course, that doesn't make a whole lot of sense.
