Answer:
4x = y – 5

-2
Y

5
-3
(X,Y)
(-1,1)
(0,5)
(-2,-3)
Put x = - 1
∴ 4(-1) = y – 5
∴ -4 + 5 = y
∴ 1 = y
∴ y = 1
Put x = 0
∴ 4(0) = y – 5
∴ 0 = y – 5
∴ y = 5
Put x = - 2
∴ 4(-2) = y – 5
∴ - 8 = y – 5
∴ - 8 + 5 = y
∴ -3 = y
∴ y = - 3
y = 2x + 1

Put x = 0
∴ y = 2(0) + 1
∴ y = 1
Put x = 1
∴ y = 2(1) + 1
∴ y = 2 + 1
∴ y = 3
Put x = 2
∴ y = 2(2) + 1
∴ y = 4 + 1
∴ y = 5
