1. (a) Complete the table below by calculating the distance traveled by a vehicle moving at 30 miles per hour.

Time (hours) 0 1 2 3 4
Distance (miles) 0 30 60 90 120


1. (b) Plot the time and distance values on the axes below.



1. (c) Calculate the slope of the line (Rise/ Run). What do you notice about the slope of the line and the vehicle's unit rate or speed in miles per hour?

The slope of the line is 30. The slope of the line and the unit rate are the same.

2. Drawn a line from each of the unit rates (m.p.h.) to the graph and slope that they match.

30 m.p.h. 40 m.p.h. 20 m.p.h.
40 m.p.h. 20 m.p.h. 30 m.p.h.

Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways. For example, compare a distance-time graph to a distance-time equation to determine which of two moving objects has greater speed.
