ANSWER
The equation is
EXPLANATION
Let the equation be
where
is the slope of the line.
We substitute this value to obtain,
Since the line passes through
we can use this point to determine the value of c.
We substitute this point to obtain,
Our equation now becomes
We can write this in standard form as
In general, you're calculating the magnitude of average velocity. In fact, speed is a vector, and as such it also has a direction and orientation.
So, if you compute the average speed, you're assuming that you went directly from point A to point B, which is basically never the case.
If, instead, you actually moved on a straight line from point A to point B, then the two quantities are the same.
