Maddox starts hiking from the main entrance to a trail. Penny starts her hike from the same entrance a little while
later. The equations below represent the distance, d, in
yards, that each person is from the entrance of the trail m
minutes after Penny starts hiking from the entrance.
Maddox: d
40m + 200
Penny: d= 50m

Y=3.6x is direct variation. The constant is 3.6
8y=2x is the same as y=0.25x. It is direct variation, and the constant is 0.25

1. Assuming "dinners made" is on the y-axis, DV is y=2x. The constant is 2

2. This is not direct variation, and therefore does not have a constant of variation
