So slope is known as rise over run, or x/y. in your case of 3/4, the slope is y=3 and x=4. The slope is equal to the growth rate. It measures steepness, so in real life you could apply it to finding the steepness of a hill for construction, or perhaps how steeply your speed grows from 0 to 100 when driving a car.
I did the problem myself and my teacher always said thatif you don't get the exact answer then round to the closest one. The answer that i got was 31,808.6, the closest one to that would be letter C.
