What is the difference in height between an albatross flying at 100 m above the surface of the ocean and a shark swimming 30 m below the surface?

 130 meters

Step-by-step explanation:

We have to let the "surface of the ocean" be at 0 height.

So,

anything above surface has POSITIVE height

and anything below surface has NEGATIVE height

The albatross is 100 m above, so we can say its height is:

+100 meters

The shark is 30 m below, so we can say its height is:

-30 meters

The difference in height is thus:

100 - (-30) = 100 + 30 = 130 meters

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

it is true

all the combinations add up i used   calculator
