The table shows the charges for using an internet service. nicholas use the internet service for 16 hours and 40 minutes last month. a.) under which plan would he have to pay less? b.) how much less?

plan a- upto 10 hrs : $6

every subsequent 1/2 hour: $1

plan b- upto 12 hours: $4

every subsequent 1/2 hour: $2

( break down answer ! )

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
