Answer:
Step-by-step explanation:
If you have a $8-off coupon at a fabric store. It means that if the original price of an item is $x, the price that would be paid will be x - 0.08x = $0.92x. Therefore,
If you buy fabric that costs $5.50 per yard, it means that x = 5.5. The cost of the fabric will be
0.92×5 = $4.6
An equation that models the total amount of money y, that you pay if you buy x yards of fabric will be
y = 0.92x
To plot the graph, we will pick different values for x and find the corresponding y values. It becomes
When
x = 1, y = 0.92
x = 2 y = 1.84
x = 3, y = 2.76
x = 4, y = 3.68
On the graph attached, the y axis represents the amount of money that will be paid in $ while the x axis represents the number of yards of fabric.
The scale used is
2cm to 0.5 units on the y axis
2cm to 1 unit on the x axis
