What is linear equation?
Linear equation is equation in which each term has at max one degree. Linear equation in variable x and y can be written in the form y = mx + c
Linear equation with two variables, when graphed on cartesian plane with axes of those variables, give a straight line.
Given the When the car begins, it is 200 miles from Kingston. After 2 hours, it is 80 miles from Kingston. Therefore, the speed of the car can be written as,
m = (200-80) miles / (0-2)hours = -60miles per hour
Since, the total distance is 200 miles, and the relation between the distance and the time is linear we can write the function that describes the car's distance from kingston is,
y = -60x + 200
Hence, the correct option is B.
