Question

can someone check my answer ?
The graph below is represented by which system of inequalities?

-4x + 2y >= 8
y < -x + 4

-4x + 2y < 8
y <= -x + 4

-4x + 2y >= 8
y > -x + 4

-4x + 2y >= 8
y < -x + 4

Answer 1

-4x + 2y >= 8
y < -x + 4 my answer

Answer 2

Im pretty sure you got it right!

Answer 3

are u sure ?

Answer 4

The line y=-x+4 is dotted, so look for y < -x+4: >> option A or D.
(0,0) is in the shaded area. Try if it fits the other inequality of A and D:
A: -4*0 + 2*0 = 0 >=8 FALSE
D: same as the one at A.. .hmm, there doesn't seem to be any good option:

Try (0,0) with both inequalities: the >=8 options are wrong.
That only leaves option B, but that says y<= -x+4, so that would not give a dotted line!

I say: they are all wrong!

Answer 5

well which would be best ?

Answer 6

If you can live with the dotted line, then I'd pick B.

Answer 7

oh okay thanks.
