Slope is rise over run, or the change in y over the change in x. So, you go up vertically then directly horizontal and whatever the change is is the slope.
For example, the first one is -1/3. It's slope is going down to the right, so it's negative . It goes down 1 (y value) and over to the right 3 (x value). Since it goes down and to the right it is a slope of -1/3.
Answer:
533.33 ft/min
Step-by-step explanation:
