Answer:
The x axis in the function represents, the number of hours after 7:00 A.M. , the person reaches her car. The person reaches the car at 1:00 P.M.
Step-by-step explanation:
The x axis denotes the no. of hours and and the y axis denotes the distance from the car.
X Intercept is a point where the line intersects the X axis, we can easily notice the fact that at that point, y=0 ie. The person has reached his/her respective car.
The line intersects x at 6.
Therefore, a total of 6 hours are taken from the beginning of the hike.
Thus, the person reaches the car at 1:00 P.M.
One way to do it is with calculus. The distance between any point

on the line to the origin is given by

Now, both

and

attain their respective extrema at the same critical points, so we can work with the latter and apply the derivative test to that.

Solving for

, you find a critical point of

.
Next, check the concavity of the squared distance to verify that a minimum occurs at this value. If the second derivative is positive, then the critical point is the site of a minimum.
You have

so indeed, a minimum occurs at

.
The minimum distance is then
Answer:
you did not say which question to answer
Step-by-step explanation:
Answer:
Slope is the difference between the y-coordinates divided by the difference between the x-coordinates.
