The unit rate refers to the slope of the line which passes through the given points. So, we need to find the slope with the following formula


m=(y_2-y_1)/(x_2-x_1)

We are going to use points (4,5) and (8,10).


m=(10-5)/(8-4)=(5)/(4)

Therefore, the unit rate is 5/4.

An interpretation of this unit rate is: while the vertical coordinate varies 5 units, the horizontal coordinate varies 4 units.
