X-AXIS: time in Minutes

Y-axis: DEPTH IN FEET

Equation: y=6x-18

Y-int: -18 ft

X-int: 3 min

Slope: 6 ft per min

There once was a dolphin who lived 18 feet below sea level. He was out for his daily swim. He decided he wanted a breath of fresh air, so he swam up at 6 feet per second.

(3,0) it takes 3 minutes to reach sea level

(0,-18) he started from his home at -18 FT.

Slope & Y-int change: if the dolphin swam faster he would reach sea level faster, making the graph steeper.
