Before Cole walks his dog, his activity tracker shows he has already walked 3.8 miles. He and his dog walk 2.6 miles per hour. Write a linear equation in slope-intercept form for the number of miles, y, after x hours of walking. Find the number of miles on Cole's activity tracker after 1/2 hour of walking.

a)

b) 5.1 miles

Step-by-step explanation:

Given

Required

Determine the linear equation

Represent distance with y

Represent time with x

Distance can be determined using:

This gives:

b) Solve for y when x = 1/2

To do this, we simply substitute 1/2 for x in

1: -2 3/4, -2 1/2, -14, 0, 3, 8 1/3

2: -4, -3, -2 1/2, -2 1/4, 3 1/4,

step-by-step explanation:

c-   36
