Acar that travels along the highway to denver at a steady speed. when it begins, it is 300 miles from denver. after 3 hours, it is 180 miles from denver. which function describes the car's distance from denver?

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

add 5 subtract 1

step-by-step explanation:

the answer is b.
