Answer 1

Step-by-step explanation:

(1) When x = 2 ; y=2

(2) When x = -2 ; y= 4

(3) When x = 4 ; y= -2

(4) When x = 5 ; y = -1

Answer 2

Step-by-step explanation:

1)Let x=0

0+y=4

y=4

2)Let x=1

1+y=4

y=4-1

y=3

3)Let x=2

2+y=4

y=4-2

y=2

4)Let x=3

3+y=4

y=4-3

y=1

x=0 y=4

x=1 y=3

x=2 y=2

x=3 y=1
