The graph below shows a line of best fit for data collected on the amount customers spent in relation to the discount they received. The equation of the line of best fit is y = 25x + 7.5. What does the y-intercept represent? A.
the discount per item

B.
the number of items purchased

C.
the discount received by a customer who did not make a purchase

D.
the amount spent by a customer who did not receive a discount

D. the amount spent by a customer who did not receive a discount. is your best answer choice.

Step-by-step explanation:

x stands for the "discount received" (shown in table)

y stands for "amount spent (in dollars)" (shown in table)

In the equation:

y = mx + b

y = (x , y)

m = slope

x = (x , y)

b = y-intercept

~

In this case, the y-intercept stands for the amount spent ($7.50) when the discount received is 0%. When the customer does not receive any discount (nor do they spend any extra money), they must pay a flat fee of $7.50.
