At a warehouse the employees can unload 18 trucks in 6 hours what is the unit rate for unloading trucks

18 trucks/ 6 hours

divide top and bottom by 6

3 trucks/ hour

The unit rate is 3 trucks per hour

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
