Slope Which of these do you think has the biggest slope A or ? 

A. 
B. 
Why would you say that? Can you explain using the words rise and run? The answer is that The slope of A is greatest because the Rise/Run of A is bigger than the Rise/Run of B. 

A.  B. 
Which slope is Positive A or B? The answer is Which cyclist needs to make the most effort? A requires more effort than a level road ==>A is positive B requires less effort than a level road ==> B is negative.

The slope is measured by comparing how much the
rise in the road for example over the distance it takes for the rise. The example shows a rise from 1 to 4 which is (41) =3. Rise=3 The run is from 1 to 4 also so it is (41)=3 as well. Run=3 Slope = Rise/Run = 3/3 = 1 

In general the formula for the slope can be given by
