For questions #1-4

Question 1

1.

Create a graph of all the data points from the table. Draw a line that would extend to the edges of the plane. Use the graph to estimate the number plates prepared after 6 minutes.

Question 2

2.

Based on the table, what would be the correct slope (m) of the line?

16 plates per minute

6 plates per minute

4 plates per minute

5 plates per minute

Question 3

3.

Based on your graph in question 1, how many plates would have been already prepared at the start of the server's shift?
Hint: This is the initial value when x = 0 also known as the y-intercept of the graph.

Question 4

4.

Use the slope and y-intercept of the graph in question #1 to write an equation of the line in slope intercept form. Let y = the number of plates and x = the number of minutes.

Question 5

5.

Does the graph have a positive or negative slope?

positive

negative

Question 6

6.

Estimate the y-intercept and interpret its meaning.

$3 per cheeseburger

$2.50 total cost of cheeseburger with toppings

$2.25 per cheeseburger with no toppings

$2 per topping

Question 7

7.

Does the graph have a positive or negative slope?

postive

negative

Question 8

8.

Estimate the y-intercept and interpret its meaning.

6000 hours to drain the pool

300 gallons per hour

24 hours to drain the pool

6000 gallons of water remaining in the pool

Question 9

9.

Hint: Use the coordinate pairs: (2, $49) and (4, $67) to find the slope and y-intercept before writing the equation in slope-intercept form.
Let y = the total cost of the cable package and x = the number of movie channels

Question 10

10.

Hint: Use the coordinate pairs: (12, $61) and (18, $79) to find the slope and y-intercept before writing the equation in slope-intercept form.
Let y = the total cost of the bouquet and x = the number of roses
