Question

You are driving from Kansas City to Denver. The distance (in miles) you

are from Kansas City can be represented by the equation y = 70x + 25
where y represents the distance from Kansas City in miles and x represents
the number of hours you have been driving.
What is the slope of the line represented by the equation?


What does the slope represent in the context of this problem?


What is the y-intercept of the line represented by the equation?


What does the y-intercept represent in the context of this problem?

Answer 1

The slope is 70

The slope represents the speed of your car

Explanation:

The slope is 70, y = mx + c, where m is the slope

The slope represents the speed of your car

speed = distance/time

speed x time = distance

As y represents the distance you travel, x is the time, slope is the speed, you get the distance travelled.
