This equation shows how the distance Tess runs depends on the number of track practices she attends.

d = p + 8

The variable p represents the number of track team practices she attends, and the variable d represents the distance run in miles. How many track practices would it take for Tess to run 11 miles?

practices

Step-by-step explanation:

Let

d ----> distance Tess runs in miles

p ---> the number of track practices she attends

we have

This is a linear equation in slope intercept form

where

The slope or unit rate is

The y-intercept (value of d when the value of p is equal to zero) is

so

For d=11 miles

substitute in the linear equation and solve for p

solve for p

n
