  1. 5-4 Point-Slope Form Objective: To write and graph linear equations using point-slope form.

  2. 5-4 Point-Slope Form • Start with Getting ready on Page 315. • Answer all questions.

  3. 5-4 Point-Slope Form • The point slope form of a nonvertical line with slope m and through point (x1 , y1 ) is • y - y1=m(x - x1 ) • y-coordinate x-coordinate • slope

  4. 5-4 Point-Slope Form • Comes from definition of slope: HOW??? • m = y - y1 y - y1=m(x - x1 ) • x - x1

  5. 5-4 Point-Slope Form • Example 1: A line passes through (-3, 6) • And has a slope of -5. What is equation? • y - y1=m(x - x1 )

  6. 5-4 Point-Slope Form • Example 2: Graph y -1 = (x – 2)? • Step 1: Graph pt • Step 2: Count slope • Step 3: Draw a line

  7. 5-4 Point-Slope Form • Example 3: What is equation of graph? • Step 1: Find Slope • Step 2: Use pt-slope form • Step 3: Use any point

  8. 5-4 Point-Slope Form • Example 4: What is equation from table? • What does slope and y-intercept ept represent?

  9. 5-4 Point-Slope Form • HW p. 318 9- 23 ODDS
