C

Step-by-step explanation:

In slope intercept form y=mx+b

m is your rate of change/ slope

since the slope is +5

This means that your rate of change, in this case elevation, is 5 feet per minute.

As for b which is your y intercept, the -30 can be represented by the point (0,-30) on a graph it would be -30ft below the x axis. Meaning that if the diver lets say is the point he is 30 feet below sea level and acsending at a rate of 5 feet per minute.
