PLEASE HELP I WILL GIVE BRANLIEST

Sarah is self-publishing her 300-page novel and wants to estimate the printing costs.

Answer the questions to estimate the cost of printing a 300-page paperback book.

1. What is the y-intercept for the trend line? What is the real-world meaning of this point?

2. One point on the trend line is (200, 6). Using this point and the y-intercept, find the slope of the trend line. Show your work.

3. What is the real-world meaning.of the slope?

4. Use the slope and y-intercept to write an equation for the trend line in slope-intercept form.

5. Use your equation to estimate the cost of printing Sarah's 300-page book.​

1. Y-intercept b=5

That means it has a 5.00 starting fee.

2. Using the formula (Y2-Y1)/(X2-X1) we will find the slope between the two points.

Point one (X1 and Y1) will be the Y-intercept.

X1,Y1 = (0, 5.00)

Point 2 (X2 and Y2) will be the point on the trend line.

X2, Y2 = (200, 6.00)

Plug in:

(6.00 - 5.00)/(200 - 0) = 00.5 or 1/200.

3. When printing 200 pages each page will cost $.005.

4. .005x+5

5. .005x+5

.005(300)+5=6.5

good luck♡♡!!
