This math review document contains a word problem about two boys, Colin and Drew, walking to school at different rates. It then provides 8 questions to complete, including: 1) Making a table showing the distance each boy walks in the first 5 minutes. 2) Writing equations to model Colin and Drew's distances over time. 3) Identifying when Colin will catch up to Drew based on the information in the table. 4) Interpreting the point (2, 750) in the context of the walk to school. 5) Identifying the coefficient and y-intercept of three equations. 6) Determining if two tables show linear or nonlinear relationships and explaining the reasoning.

Drew stops at Colin’s house on the way to school. Colin’s mother says that Colin left a
few minutes ago. Drew leaves Colin’s house, walking quickly to catch up. Colin
already has a 500 meters head start to school. Drew is walking at a rate of 250 meters
per minute while Colin is walking at a rate of 125 meters per minute.
1) Make a table showing the distance each boy walked during the first five minutes.

3) Write an equation for Colin and Drew where (t) represents time and (d) represents the
distance walked.

4) After how many minutes does Colin catch up to Drew? WHERE IS THIS ANSWER
IN THE TABLE?
5) What does the point (2, 750) mean in context of the walk to school? (BE SPECIFIC!)
6) If you were to graph the data, at what point would the lines intersect? ________
7) Identify the coefficient and the y-intercept of each equation:

2. a) y = 5x - 2 b) y = -2x + 7 c) y = 6 + 3x
