PLEASE ANSWER I REALLY NEED HELP

Determine which of following points lie in the solution set of the inequality y >= 2x-4 and which do not. Justify each choice.

a) (5,4)
b) (0,1)
c) (10,16)
d) (2,-1)

Respuesta :

Plug in the x and y values in the inequality.
A) 4>2(5)-4 C) 16>2(10)-4
4>6 16>16


B) 1>2(0)-4 D) -1>2(2)-4
1>-4 -1>0

Solution B makes sense since 1 is greater than -4. Solution A and D does not because they are less than the y value. Solution C isn't either because the inequality is saying the y value is greater than the x value and not equal to.
