Question

A restaurant that makes deliveries plotted data points on a scatter plot showing the relationship between x, the number of miles between the restaurant and the point of delivery, and y, the number of minutes between the time an order is placed and the time it is delivered. The equation of the line of best fit for the data was y = 2x + 6

Which conclusion is correct?
A) the y - value for each of the data points on the plot was 2x + 6
B) The time of delivery for the next order is found by evaluating the expression 2x + 6
C) It takes the restaurant about 6 minutes to prepare each order for delivery
D) It takes the restaurant about 2 minutes to prepare each order for delivery

Answer 1

Given:
y = 2x + 6
x - the number of miles between restaurant and point of delivery
y - the number of minutes between the time an order is place and the time it is delivered.

The correct conclusion is:
C) It takes the restaurant about 6 minutes to prepare each order for delivery


2x is the time it takes to deliver the order, every mile is traveled within 2 minutes.
6 is the number of minutes it takes to prepare the order before it will be set out for delivery.
