Ashark is at −80 feet. it swims up and jumps out of the water to a height of 15 feet. write a subtraction expression for the vertical distance the shark travels.

Step-by-step explanation:

So the total distance the shark travels is from that -80, past 0, where the water is, to 15 feet above the water.  Think of it on a graph, or number line where the shark goes from -80 to 15.  In that case 0 would be where the water is.  

This value is 95.

I am a bit apprehensive in giving an answer since the wording of the question is a bit unclear, but I think you would give 95-80=15.  As long as you understand the shark traveled a total of 95 feet upward though you at least have an understanding of a pretty important part of it.  

last one.

step-by-step explanation:

last one.

generally speaking, the others follow some sort of pattern that correlates to either linear (looks like a straight line) or sinusoidal (looks like an s).

the last one is just a random cloud of points that doesn't correlate to any particular known order.
