Answer 1

lets do it together

Answer 2

first we isolate y

Answer 3

so subtract 4x to both sides

Answer 4

\[y=-4x-6\]

Answer 5

now that you do that replace all of the (x,y) and pplug it in the equation and see if it is true or false

Answer 6

so lets do the first choice

Answer 7

\[-2=-4(-2)-6\]

Answer 8

is this true, to find out if it is true simplify it

Answer 9

nowoi am confused

Answer 10

-2=8-6
-2=2
false

Answer 11

now u try it :) hope i helped

Answer 12

@wakeboarder13 u see the first equation, i made, plug in the (x,y) in to the equation to see if it does equal the same for ex. 5=5

Answer 13

what would it be

Answer 16

Take each coordinate, one at a time, and fill in its x value and its y value into your equation. Taking the first one, (-2, -2), you get 4(-2) + (-2) = -6. Do the math then and find out if this coordinate makes the equation true. In other words, does sticking in the -2 for x and the -2 for y make the equation = -6.

Answer 17

so what would it be

Answer 18

For the first coordinate 4(-2) + (-2) = -6, the result is -10, so the first coordinate, A, is not your answer. Try the second one 4(2)+ (-2) = -6. Does this coordinate make the equation = -6? No this one comes out to a positive 6 and positive 6 does not equal -6. Try the third one, C.

Answer 19

4(-2)+2 = -6. 4(-2) is -8. -8 + 2 = -6, so C is your answer. Do you understand that?

Answer 20

its c?
