Answer 4

D.

Answer 5

Welcome to OpenStudy!

Since you are given only ONE equation in TWO unknowns, you cannot find x and y without further info.

However, you can substitute the x- and y-coordinates of each given point into the given equation to see whether the equation is or is not true. If not true, keep going until you identify the point whose coordinates do satisfy the given equation.

Answer 6

it would be D

3(-2)+5(3)=-6+15=9

Answer 7

C would come out to -9 which is not what we are looking for

Answer 8

It's EQUALITY that is important here. The two sides of the equation must be EQUAL. If they are not, the equation is not true. In such case, move on to the next point and repeat the process.
