runrise

change in y-value over change in x-value
change in y-value over change in x-value

x2−x1y2−y1
the fraction with numerator x sub 2 minus x sub 1 and denominator y sub 2 minus y sub 1

riserun
the fraction with numerator r i s e and denominator r u n

y2−y1x2−x1

Answer 1

The three responses that properly describe "slope" are:

1. change in y-value over change in x-value - This is a direct definition of slope.
2. riserun - This can be interpreted as "rise over run," which is another way to describe how slope is calculated.
3. y2−y1x2−x1 - This is the formula for calculating the slope using the coordinates of two points.

(Note: The response "the fraction with numerator rise and denominator run" is similar but not as precise as the alternatives provided above.)
