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.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

answer: 0.64
