Answer/Step-by-step explanation:

If in the value of x into each given equation to find y:

✔️x = 3.5,

y = -2(3.5) + 4

y = -7 + 4

y = -3

✔️x = -1,

y = ½(-1) + 11 = -½ + 11

y = (-1 + 22)/2 = 21/2

y = 10.5

✔️x = 0

0 + y = 1

y = 1

✔️x = 4,

2(4) - y = 5

8 - y = 5

-y = 5 - 8

-y = -3

Divide both sides by -1

y = 3
