chewing gum day! 9.30.22 Prepare to write the warm-up in your spiral. Warm-up Notes: Graphing Standard Form Notes: Converting to Standard Form Practice Who is the funniest person (it can be someone you know OR a celebrity)? Chromebook, Notebook, Pencil, Calculator
Warm-up: Point-Slope Form Directions: Write each into point-slope form. 1. (-2, 3); m = ½ 2. (4, -8); m = -3 3. (0, -8); m = -4/3
Warm-up: Point-Slope Form Directions: Write each into point-slope form. 1. (-2, 3); m = ½ 2. (4, -8); m = -3 3. (0, -8); m = -4/3 y - 3 = ½(x + 2)
