Name: Writing an Equation in Slope Intercept Form Given a Point and the Slope Guided Example: Write the equation of the line with slope 3 that passes through the point (-1 , 6). Step. Work l. Rewrite the equation mx + b 2. Substitute the given slope and the coordinate m = 3 and (x, y) = (-1, 6) 3. Simplify and Solve for b. -3 4. Substitute the slope and y-intercept into the slope-intercept formula Example #2 m = 2 and (-1, 5) +2 Try One! m = I and (-2, ) y cmX+b +1 Example #3 m = -2 and (-2, -2) y mx e b -ID?-b DIY! m = -l and (4, 5) mK*b
