You randomly survey students about year-round school. The results are shown in the graph
Year-Round School
The error given in the graph means that the actual percent could be 5% more or 5% less
than the percent reported by the survey.

plug in the numbers into the variables

your answer is a

answer: 72: 111

step-by-step explanation:

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.
