Elijah's workout at the gym consists of just the elliptical and treadmill. After burning 450 miles
on the elliptical machine, Elijah switched to the treadmill. If he is burning 12.5 calories per
minute on the treadmill, find the total number of calories he will have
burned during his workout if he spends 30 minutes on the treadmill.
I need to define the variables and write this in a slope and y-intercept form but I’m not sure how to do that
