Unit 2 Day 4 Slope-Intercept Form

Slope-Intercept form of a linear equation Y= mx + b m= Slope (always write as a fraction), B = Y-Int Slope Intercept Form from Two Points: Find Slope What information do I know? Point and Slope, so Point Slope Form Get rid of fraction if necessary and then distribute. Reorganize into slope intercept form.

Graphing from Slope-Intercept Form Identify Slope and Intercept (0,b) Plot the y-intercept Use the Slope (rise over run) from the intercept to find second point. Connect the points.
