Question

Help!! I have no clue

Answer 1

So we know that an ordered pair looks like (x,y), right? For this inequality, we're supposed to plug in the values of x and y. If it isn't true, then the inequality does not represent the ordered pair.

First option: (0,1)

`2x + 3y \geq -1` -->
`2(0) + 3(1) \geq -1` -->
`5 \geq -1`

So this option is correct.

Second option: (-2,1)

`2x + 3y \geq -1 --> 2(-2) + 3(1) \geq -1`

-->
`-4 + 3 \geq -1 --> -1 \geq -1`

This is also correct.

Third option: (-6,0)

`2(-6) + 3(0) \geq -1 --> -12 \geq -1`

This is not true, so this option is not correct.

Fourth option: (0,-1)

`2(0) + 3(-1) \geq -1 --> -3 \geq -1`

This is not correct.

Fifth option: (2,-1)

`2(2) + 3(-1) \geq -1 --> 4 - 3 \geq -1`

This is correct.

Answer 2

okay so you just plug in the x and ys. x is the first number, y is the second. then you just do them all out
