Question

Please help me thank you sooo much

Answer 1

Answer: B

Explanation:

The answer has to be either A, or B, because when x input is negative, the y input is positive. Visa versa.

Then just input x and y into the equation to see which answer is correct.

First let’s do A: 12=-2(-3)-6

12=6-6

12 doesn’t equal 0, so A is incorrect

So then B is the obvious solution, but let’s solve it to make sure: 12=-2(-3)+6

12=6+6

This equation is true, so the answer is B

Answer 2

Explanation:

Firstly you must understand you want to get the value of y.

So put in values into equation which make x.

To understand here lets look at y = 0

if y is to be 0 then x is 3.

If we substitute this value into equation (B) we get the result.

Now we have identified our answer, all is left is to substitute all other values of x and see if y are true.

So , we can see B is the answer
