Answer 1

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

Linear equation

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)

$Slope = \frac{y_2-y_1}{x_2-x_1} =\frac{192-64}{60-20} =3.2$

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