P(2,1), Q(11,1), and R(8,7)

M and N are the midpoints for segment PR.and segment QR respectively.How do these lengths MN and PQ compare now? What do you think you can conclude about the lengths of these segments? (In your answer, make sure to include your coordinates for all points, the lengths of the segments, and your conclusion.)

M and N are the midpoints of segment pr and segment qr respectively.

Using graph paper, repeat this process from the last problem using different coordinates for P, Q, and R. How do these lengths MN and PQ compare now? What do you think you can conclude about the lengths of these segments? (In your answer, make sure to include your coordinates for all points, the lengths of the segments, and your conclusion.)

You need to draw a line and label two points P and R. Using a line graph will make this easier to do. Then you label the midpoint of that line segment M, since M is the midpoint of PR. Then you need to add a point labeled Q anywhere (either within the line segment PR or outside the line segment but on the same line). Then you need to add a point labeled N at the midpoint between Q and R (hence N being the midpoint of QR). If you did this on a line graph, then you should easily have the coordinates of each point and the lengths of each line. Do this again changing where you put the points, but still following the rules and you should see a pattern.
