Answer 2

Since the question is multiple choice, you can plug in the answers.

Begin by plugging in

Answer 3

-4 to the x 0 to the y. is the statemet then true?

Answer 4

If not, try the next pair, until it is true.

Answer 5

Plug in. Remember (x,y) if its true than its a solution :)

Answer 6

If its not true than its NOT a solution.

Answer 7

So if I plug in -4 and 0 is this what the equation would look like?
-4(less than or equal to) -2(-4)-3

Answer 8

Not quite, I think you got your x and y mixed up. (:

\[\large y \le-2x - 3\]
As amelia said, plug in the x and y values.
(-4, 0)
(x, y)

x = -4
y = 0

\[\large 0 \le-2(-4) - 3\]
Solve the equation. If its true, you have your answer. If not try each of the other choices.
