Which hill described in the table is the steepest? Explain.' (Table) Street Horizontal Distance (ft) Vertical Rise Dixie Hill 80 40 Bell Hill 80 20 Liberty Hill 80 60 A.Bell Hill; it rises 1 foot for every 4 feet of horizontal travel. B.Dixie Hill; it rises 2 feet for every 1 foot of horizontal travel. C. Liberty Hill; it rises 4 feet for every 3 feet of horizontal travel. D. Liberty Hill; it rises foot for every 1 foot of horizontal travel.

Do you know what slope is? Not to belittle your intelligence, but this question is based on the slopes of the streets (aka their steepness). The horizontal distance is the x value or the run, and the vertical distance is the y value or the rise. If Dixie Hill has a rise or 40 and a run of 80, its slope is rise over run or 40/80 or 1/2. It rises one unit for every 2 it moves to the right. The slope of Dixie Hill is 1/2. See that?

Yes, i get it. SO 20/80 would be 1/4. And 60/80 would be 3/4... So Liberty hill. C.

Let me go back and read the question! lol

OpenStudy (anonymous):

lol ok

OpenStudy (imstuck):

The one with the greatest slope is 3/4 so you are correct! Yay!

OpenStudy (anonymous):

yay! But is it C or D?

OpenStudy (imstuck):

It's C. Because the slope doesn't even have a 1 in it, it can't be D. Plus I think you left out a number by the "rises___foot"! No worries! It's C.
