Question

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

y > -3x + 3
y > x + 2

a (2, -5)

b (-2, 5)

c (2, 5)

d (-2, -5)

Answer 1

check the points
example: does (2,-5) make sense?
x = 2, and y=-5
we have
y>-3x+3 and y>x+2
so
-5>-3*2+3? ---> -5>-3? this tells us already there is a problem with the first point...so we move on to the next.
understand?

Answer 2

you just need to put each point into inequalities to see which point fits both of them

Answer 3

thank you :-)
