Question

Which ordered pair is not in the solution set of y > 2x + 1 ?

[1] (1,4) [2] (1,6) [3] (3,8) [4] (2,5)

Answer 1

You can replace the x,y values in the inequality and see if it's valid or not.

Answer 2

For example,in [1]: We have x=1, y=4. That is: 4>2*1+1
So we have 4>3, which is valid. So the first tuple ([1]), IS in the solution set of the inequality. The same you do for the rest.
