The slope of the line representing the linear graph is a rate of 3.2 meters per second.
<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 meters and x represent the time in seconds. Hence:
- Using the points (20, 64) and (60, 192)

The slope of the line representing the linear graph is a rate of 3.2 meters per second.
