sorry forgot the negatives

Answer 2

replace the coordinates and try
no one is right !!

Answer 3

substitute the x value from each ordered pair into the equation to see which y value you get

Answer 4

Yeah...I tried each one, and none of them work.

Answer 5

ok now C is right
3(6) + 7(-1) = 18-7 =11

Answer 6

Hoblos, you have to ADD them...you can't subtract.

Answer 7

yeah.... 18 + (-7) = 18 - 7 =11

Answer 8

Ooohh. It's a negative 7?

Answer 9

when you multiply it by (-1) it becomes negative
