Question

x+y=0
3x-3y=0
(-1,1)

Answer 1

yes that is correct because when u plug in the point into the function you get 0=0

Answer 2

i get -1=0,-6=0

Answer 3

no you get -1+1=0 when you plug in the coordinates to the first function and for the second you get 3(-1)-3(1)=0 you get 0=0.

Answer 4

there both true because left side =right side.

Answer 5

i thought 3(-1) =-3

Answer 6

this what i did 3(-1)-3(1)=0
-3-3=0
-6=0

Answer 7

sorry @jinan you right i forgot about the other negative for the second function. So the top function is true and the one below it is false.

Answer 8

x+y=0 this what i get for this one
-1+1=0
-1=0
(-1,1)

Answer 9
