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)

try pluging in the points into both sulotions and see if they are both right

I don't get it

Ex.)
 For (5, 1): x = 5, y = 1 -- insert these into your two inequalities and see what comes out

y < -3x + 3
 1 < -3(5) + 3
 1 < -15 + 3
 1 < -12  (false!)
     So, (5,1) is not in the solution set because it doesn't work for those inequalities.
