What is the slope of a line parallel to line a?
a. 7/4
b. -7/4
c. 4/7
d. -4/7

The line A passes through two points, those are:
(x₁,y₁) = (0,4)
(x₂,y₂) = (-7,0)

Use the following formula of slope
m = (y₂ - y₁) / (x₂ - x₁)

Plug the numbers into the formula
m = (y₂ - y₁) / (x₂ - x₁)
m = (0 - 4) / (-7 - 0)
m = -4/-7
m = 4/7

The answer is option c

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.
