Two cyclists, A and B, are going on a bike ride and are meeting at an orchard. They left home at the same time. Functions A and B give their distance from the orchard, in miles,
after riding for x hours. The functions are defined by these equations:
A(x) = -21% + 48.5
B(x) = -16.8x + 42
For each question, explain or show your reasoning.
a. Which cyclist lives farther away from the orchard? How do you know?
b. Who will get to the orchard first? Explain your reasoning.

Ted and meg have each drawn a line on the scatter plot shown below: the graph shows numbers from 0 to 10 on x and y axes at increments of 1. dots are made at the ordered pairs 1, 8 and 2, 7.5 and 3, 6 and 4, 5.5 and 4.5, 4.8 and 5, 4 and 6, 3.5 and 7, 3 and 8, 1.9 and 9, 1.2 and 10, 0. a straight line labeled line p joins the ordered pairs 0, 8.5 and 10.1, 0. a straight line labeled line r joins the ordered pairs 0, 8.5 and 7.8, 0. which line best represents the line of best fit? line p, because it is closest to most data points line p, because it shows a positive association line r, because it is closest to most data points line r, because it shows a negative association
