Find the distance between the points (-8/5,2) and (2/5,2)
Calculate the differences in x and y coordinates. Call them dx and dy.
Hint: dy is zero in this case.
The distance D between them is
D = sqrt(dx^2 + dy^2)
In this case, D = dx
Hint: dy is zero in this case.
The distance D between them is
D = sqrt(dx^2 + dy^2)
In this case, D = dx
