1. Point-Slope Formula

2. Where m is the slope and b is the intercept
What we Know so far….
Slope Intercept Form
Where m is the slope and b is the intercept

3. What is the slope and y-intercept of each equation?
Y= x + 3
Y= -5x +4

4. The New Stuff… Point- Slope Formula
Point- Slope form is:
Where m is the slope and (x1,y1) is the given point

5. Point Slope Formula
A formula used to calculate the equation of the line algebraically.
used when given the slope and 1 point.

6. I DO
What is the equation of the line that passes through the points ( 2, 6) and (3, 7).

7. I DO
Find the equation of the line between (14, 52) and (29, 97)

8. We Do
( -4, -7) and (0, 9)
2. (9, 8) and ( 12, 11)

9. You Do
1. ( -3, -6) and (20, 40)

10. Active Practice
With your partner…play Tic-Tac-Toe! You both solve the problem. Player 1 chooses a problem and you both solve it in your notebook. If player 1 gets it right, they put an X on the answer. Player 2 can get the point (an O) if player 1 does not solve it correctly. If the answer isn’t in the grid then you move forward. Then Player 2 goes. Play until you get Tic-Tac-Toe and you get blackout between you and your partner!
