a scuba diver dove from the surface of the ocean to an elevation of −99 9/10 feet at a rate of −23.5 feet per minute. after spending 14.5 minutes at that elevation, the diver ascended to an elevation of −38 9/10 feet. the total time for the dive so far was 21 1/8 minutes. what was the rate of change in the diver's elevation during the ascent? round your answer to the nearest hundredth.

the rate of change of the diver's elevation was ft/min.

answer:

200 ft

step-by-step explanation:

for the points

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
