Answer:
Step-by-step explanation:
Let x be the time (in hours) and y be the distance from Denver (in miles).
When car begins, it is 300 miles from Denver, so x = 0 hours and y = 300 miles.
After 3 hours, it is 180 miles from Denver, then x = 3 hours and y = 180 miles.
Write the equation of the line passing through the points (0,300) and (3,180). The slope of this line is
y-intercept is at (0,300), hence the equation of the line is
