  1. Bell Ringer Find the slope of the lines going through: 1. (1, 2) (3, 8) 2. (0, 5) (6, 8) Identify the slope and the y-intercept: 3. y = 6x + 2 4. y = -3x – 1 m = 3 m = ½ m = 6, b = 2 m = -3, b = -1

  2. Next Two Weeks… Mon – Midpoint Refresher Tue – Distance Formula Wed – Midpoint and Distance Problems Thur – Mini-Quiz (Midpoint & Distance) Fri – Begin Final Exam Review Mon – No School – MLK Day Tue – Final Exam Review Wed – Finals (Odd) Thur – Finals (Even) Fri – Return Final Exams

  3. GRE 504: Find the midpoint of a line segment* GRE 603: Use the distance formula The Midpoint Formula

  4. The Midpoint…(Refresher!) • The midpoint is the middle of two points on a coordinate plane. • To find the midpoint, you would find the average of the x and y coordinates, or… x1 + x2 2 , y1 + y2 2 ) (

  5. Find the midpoint! Find the midpoint of the coordinates: (2, 4) & (6, 12) I remember this! (x1, y1) (x2, y2) , ( ) 2 + 64 + 12 2 2 ( ) , 816 2 2 This is the midpoint! (4, 8)

  6. Find the midpoint and plot it! Identify the points! (5, 3) and (-3, -3) Use the formula! . ( , ) 5 + -33 + -3 2 2 . . ( , ) 20 2 2 Now plot it! (1, 0)

  7. Find the midpoint and plot it! Identify the points! (2, 8) and (-5, -5) Use the formula! . . ( , ) 2+ -58+ -5 2 2 . ( , ) -33 2 2 Now plot it! (-1 ½ , 1 ½ )
