The car is driving at 70 miles per hour which is above the speed limit on the highway
<h3 /><h3>Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and m is the y intercept.
Let y represent the distance in miles and x represent the time in hours. Hence:
- Using the points (0, 0) and (3, 200)

Bob speed limit is 66.7 miles per hour
Given a car by y = 70x. The car is driving at 70 miles per hour which is above the speed limit on the highway
