3. Demonstrate an understanding of slope with respect to: • rise and run • line segments and lines • rate of change • parallel lines • perpendicular lines. [PS, R, V]

Achievement Indicators 3.1 Determine the slope of a line segment by measuring or calculating the rise and run.

3.2 Classify lines in a given set as having positive or negative slopes.

3.3 Explain the meaning of the slope of a horizontal or vertical line.

3.4 Explain why the slope of a line can be determined by using any two points on that line.

3.5 Explain, using examples, slope as a rate of change.

3.6 Draw a line, given its slope and a point on the line.

3.7 Determine another point on a line, given the slope and a point on the line.

3.8 Generalize and apply a rule for determining whether two lines are parallel or perpendicular.

3.9 Solve a contextual problem involving slope.
