Use this guide to accompany Lesson 3.08, Semester A. Slope-Intercept Form LESSON GOALS • Use slope-intercept form of a line to identify the slope and y-intercept of a line. • Graph an equation in the form y = mx + b. • Write the equation of a line that does not pass through the origin using its graph. FLORIDA STANDARDS • MAFS.8.EE.2.6 Use similar triangles to explain why the slope m is the same between any two distinct points on a non-vertical line in the coordinate plane; derive the equation y = mx for a line through the origin and the equation y = mx + b for a line intercepting the vertical axis at b. PACING One class period, approximately 60 minutes LEARN MATHCAST: SLOPE-INTERCEPT FORM By starting out with a recipe, this MathCast introduces students to slope- intercept form by telling students it helps them see important information. Students see how to use an equation in slope-intercept form to find the slope and the y-intercept, and then graph the line. MATERIALS • reference Guide pages 120–121 • practice Activity Book pages 90–94 • Overview and Toolkit presentations KEYWORDS Students can preview definitions of keywords hyperlinked throughout the lesson. • slope • slope-intercept form • y-intercept SlOpE-INTErCEpT FOrm 163
