See the next slide

2. 5.)Write the Equation Y X

3. Bellwork Write the equations
1.) slope = 2, b=-5
y = 2x -5
2.) y-intercept = 6, m =1
y = x + 6

4. Bellwork Write the equations
3.) m = -3, b = -2
y = -3x -2
4.)slope= -2, y-intercept = 1
y = -2x + 1

5. 5.)Write the Equation
Slope - 4 Y
y = -4x -4 X
y-intercept is -4

6. Today’s Objective
To be able to write an equation of a line given two points on the line. Point-Slope (y - y1) = m (x - x1)

7. 1.) Write an equation of a line given
The points (1,6) & (3,-4)
1.) Find the Slope
m = (-4 -6)/(3-1)
m = -10/2 = -5

8. Write an equation of a line given
The points (1,6) & (3,-4)
2.) Plug in one of the points (y - y1) = m(x - x1)
(y - 6) = -5(x - 1)
y - 6 = -5x + 5

9. Write an equation of a line given
y - 6 = -5x + 5
y = -5x
y = -5x + 11

10. 2.) Write the equation of the line
(4,3) Y X
(-2,-3)

11. Write an equation of a line given
The points (4,3) & (-2,-3)
1.) Find the Slope
m = (-3 -3)/(-2-4)
m = -6/-6 = 1

12. Write an equation of a line given
The points (4,3) & (-2,-3)
2.) Plug in one of the points (y - y1) = m(x - x1)
(y - 3) = 1(x - 4)
y - 3 = 1x - 4

13. Write an equation of a line given
y - 3 = 1x - 4
y = x
y = x - 1

14. Write an equation of a line given
The points (-1,5) & (3,-3)
1.) Find the Slope
You try this one
m = (-3 -5)/(3- -1)
m = -8/4 = -2

15. Write an equation of a line given
The points (-1,5) & (3,-3)
2.) Plug in one of the points (y - y1) = m(x - x1)
(y - 5) = -2(x - -1)
y - 5 = -2x -2

16. Write an equation of a line given
y - 5 = -2x - 2
y = -2x
y = -2x + 3
