  1. Analyzing Data using Line Graphs Slope & Equation of a Line

  2. Slope  Rise over Run m = y2 – y1 x2 – x1 (3, 5) & (1, 4)

  3. You Try!!! m = y2 – y1 x2 – x1 (2, 3) & (1, 5) (-2, -5) & (1, 4)

  4. Equation of a Line y = mx + b Slope y - intercept

  5. How to find line of best fit 1.) Find slope using m = y2 – y1 x2 – x1 2.) Choose one point and plug in for “x” and “y” in the equation y = mx + b 3.) Solve for b 4.) Plug m and b into y = mx + b

  6. Find line of best fit that include the points (3, 2) and (6, 1)

  7. You try!!! (3, -2) & (5, 3)

  8. You try!! (4, -2) & (7, 5)
