SOLUTION: What is the distance between points (7,-2) and (11,-2)?

Apply the distance formula


    d = .


In your case  (,) = (7,-2),  (,) = (11,-2).


OR, alternatively, you may notice that both points lie on the horizontal line y= -2.


It makes your calculations easier/simpler:  the distance between the poins is  11 - 7 = 4 units.
