9.3.4.4 Use coordinate geometry to represent and analyze line segments and polygons, including determining lengths, midpoints and slopes of line segments

a) I can determine the slope of a line.

b) I can determine the distance (length) between points

on a coordinate plane.

c) I can determine the midpoint of a segment given

coordinates of the endpoints.

d) I can use slopes and lengths to analyze polygons.

Tutorial

This video breaks down the midpoint formula to its most basic concepts.

This video shows how the distance formula is an extension of the Pythagorean theorem.
