Question

Jordan Will hike the trail shown at a rate of 5mi/h. write a linear equation to represent the distance Jordan still has to walk after X hours. what does the Y-intercept of the equation represent?

Answer 1

using linear equation

`\begin{gathered} y=mx+b \\ \text{where} \\ m=\text{slope} \\ b=y-\text{intercept} \end{gathered}`

Therefore,

`\begin{gathered} x=\text{time in hours} \\ y=dis\tan ce \\ m=5 \end{gathered}`
`y=5x+31`

The y - intercept which is equals to 31 represents the distance he still has to walk .
