Jordan will hike the trail shown at a rate of 4mi/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 represents?

We are given rate of hike the trail = 4 miles/hour.

Let us assume number of hours Jordan still has to walk = x.

We know, relation among rate, time and distance is given by formula:

Distance = rate * time.

Let us take distance by variable y.

Therefore, we get the equation for distance:

y = 4x. y-intercept of the equation represents the distance Jordan has walked so far.
