Answer:
(a) 
(b) 
(c) 
Step-by-step explanation:
The formula for calculating the equation of line in point - slope form is given as :
where m is the slope
Given from the question :
m = - 4
= 2
= 6
Substituting into the formula , we have :




Therefore :
(a) the equation of the line in point - slope form is 
(b) to write it in slope - intercept form , we will make y the subject of the formula , which will give : 
(c) the equation of line in standard form is ; 
We use the formula
where d is distance, s is speed and t is time.


Therefore, a car would tracel 480 km.
