PRIMARY CONTENT MODULEA lgebra - Linear Equations & InequalitiesT-39 1999, CISC: Curriculum and Instruction Steering CommitteeThe WINNING EQUATIONM eaning of m = y2 y1x2 x1 in y = mx + bm = y2 y1x2 x1 is the rise ( y2 y1) over the run ( x2 x1) andm is called the slope.

To find out, suppose (x 1, y1) and (x 2, y2) are two points on the graph of y = mx + b. Then y 1 = mx 1 + b and y 2 = mx 2 + b. Use algebra to simplify y2 – y1 x2 – x1 And give a geometric interpretation. Try this! PRIMARY CONTENT MODULE Algebra - Linear Equations & Inequalities T-38
