Answer 2

Answer:

Mark me as a brainlist tanx

Step-by-step explanation:

x 0 1 2

y 10 8 6

(x, y) (0, 10) (1, 8) (2, 6)

let x=0

2x+y=10

2x0+y=10

0+y=10

y=10

let x=1

2x+y=10

2x1+y=10

2+y=10

y=10-2

y=8

let x=2

2x+y=10

2x2+y=10

4+y=10

y=10-4

y=6

x 0 1 3

y -2 0 2

(x, y) (0, -2) (1, 0) (3, 2)

let x=0

2x-y=2

2x0-y=2

0-y=2

y=-2

let x = 1

2x-y=2

2x1-y=2

2-y=2

-y=2-2

y=0

let x =2

2x-y=2

2x2-y=2

4-y=2

-y=2-4

y=2

this is correct answer
