Joe and Nate went for a walk. The system representing each boy’s progress is graphed below. Which statements about the system and scenario are true? Check all that apply.
Answer
A
Nate starts 5 miles away from Joe’s house and gets closer as he walks because the y-intercept is 5 and his distance is decreasing.
B
Nate walks at a negative speed because the slope of his line is negative.
C
Joe walks at 1 mile per hour because the line representing his progress rises 1 for every 1 it runs.
D
Nate walks at rate of 2 miles every 30 minutes because the difference in distance is 2 miles for every 30 minutes of time.
E
Joe is walking faster than Nate because his line is steeper, meaning the distance he travels is changing more quickly.
