3. 11/6/15 Lesson 3 – 4 Linear Functions Advanced Math/Trig

4. Learning Objective To write equations in standard form To graph piecewise functions

5. Write an equation in standard form Or you already know the slope and y-intercept y= mx + b y = 1x + 3 x – y = –3

6. Parallel & Perpendicular Lines Parallel Lines have the SAME slope Perpendicular Lines have OPPOSITE RECIPROCAL slopes (flip fraction & change sign)

7. Write a Linear Equation

8. 3. Write an equation in Slope-Intercept Form of the line with y-intercept of 5 and parallel to 9x – 7 = 3y Parallel slope = 3 y–intercept = 5 y = 3x + 5
