Calculating the Slope: Key Concepts and Applications

What does the 'rise' in the slope formula represent?

• The change in x-values

• The sum of y-values

• The sum of x-values

• Sum of x-values divided by sum of y-values

• Change in x divided by change in y

• Change in y divided by change in x
