Question

What is the system of equations that describes the following graph?
A3x – y > 2
x – y < -4

B 3x – y ≤ 2
x – y ≤ -4

C 3x – y ≥ 2
x – y ≥ -4

D 3x – y ≥ 2
x – y ≤ -4

Answer 1

Try to get them in the form of

y=mx+b

where m is the slope and b is the y-intercept

see which equations have the y-intercept of the graph you have.

Answer 2

d?

Answer 3

If that is the answer you came up with when finding the y-intercepts then yes that is the answer.

Answer 4

can you check if it is correct?

Answer 5

Yes you are right

Answer 6

The answer is C
not D

Answer 7

it is?

Answer 8

the y-intercept is the same in all pair of equations here, so you'll have to check if the shaded region is correctly displayed by the < and/or > signs

Answer 9

sure its c?

Answer 10

ok... so C??

Answer 11

wait wait wait, just mixed myself up here. Please hold

Answer 12

Forget my last post, I was oh so very wrong. the answer is indeed C, because y needs to be bigger than x+4 or smaller than 3x-2 to be in the shaded region, correct?

Answer 13

ok.. thanks so much
