The linear function is given by:
where y represents Alberto's speed in meters per minutes.
when his stride rate is x steps per minute.
We know that for any linear function of the type:
m represents the slope and c represents the y-intercept of the function.
<em>i.e. the slope represents the stride rate of Alberto i.e. the rate at which he is walking.</em>
<em>It represents that his speed is 0 meter per minutes when he did not took any step.</em>
