s = (d) / (t) , where s denotes speed, d, distance, and t, time
So, d is a function of t, which can be written as: d=st

We know that the general formula for the slope-intercept form is y=mx + b

We can easily notice that our function d is in fact written in slope-intercept form, with the free term b (intercept) being 0:
d = st +0

Therefore, speed is the slope of the function expressing distance as a function of time.
