Acar is traveling on a highway. the distance (in miles) from its destination and the time (in hours) is given by the equation d=420-65t. what is the practical meaning of the d-intercept? a. initially the car is 355 miles from its destination. b. initially the car is 420 miles from its destination. c. initially the car is 65 miles from its destination. d. initially the car is 485 miles from its destination.

b. Initially the car is 420 miles from its destination.

Step-by-step explanation:

The equation of a line in slope intercept form is given by :-

, where m is slope and c is the y-intercept.

Given : The distance (in miles) from its destination and the time (in hours) is given by the equation :

Which can be written as

It implies the d-intercept = 420

We know that the intercept of any function tells its initial value.

It means the initial distance of car from its destination = 420 miles

Hence, the practical meaning of the d-intercept is "initially the car is 420 miles from its destination".

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
