Using -2, -1, 0, 1 and 2 as your x values solve x+ 1/2y =1; then graph it

X + y/2 = 1
y/2 = 1 - x
y = 2(1 - x)
y = 2 - 2x

when x = -2
y = 2 + 4
y = 6
(-2,6)

when x = -1
y = 2 + 2
y = 4
(-1,4)

when x = 0
y = 2 - 0
y = 2
(0,2)

when x = 1
y = 2 - 2
y = 0
(1,0)

when x = 2
y = 2 - 4
y = -2
(2,-2)

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
