On graph paper, graph the points
Plot the points. A graph with 3 points. A (2, comma 9). B (4, comma 3). C (9, comma 6).
Draw lines to show the distance between points
Draw slope triangles for both line segments. Draw a vertical line straight down from point A, 6 units, then right 2 units to connect to point B. Then drawn a horizontal line from point B, right, 5 units, and then up, 3 units to connect to point C.
Use the Pythagorean Theorem to find the lengths of the line segments.
