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:

This car follows a line, hence its motion can be modeled by the Line equation.

In fact, we already have two points of the line, if we call the time in hours and the traveled distance in miles:

Point 1:

Since we are told the car's initial position is 300 miles in the time 0 h

Point 2:

Since we are told the car's final position is 180 miles after 3h

Let's find the Slope :

 This is the slope of the line

Now, the equation of the line is:

We already know the slope, now we have to find the intersection point with the y-axis () with any of the given points. Let's choose Point 1:

Isolating :

Then, the equation of the line is:

answer is a
