You are running a fuel economy study. One of the cars you find is blue. It can travel 30 1/2 on 1 1/4 of gasoline. Another car is red. It can travel 25 3/5 on 4/5 of gasoline. What is the unit rate for miles per gallon for each car? Which car could travel the greater distance on 1 of gasoline?

Sample Response:

Translations move every point on a figure the same distance and direction. You can use the one vertex and its image to find the rule that maps the triangle to its image. This rule can then be used to find the images of the other vertices of the triangle. Plot the vertices and connect them to form the image of the triangle.
