1. 4.2
Point-Slope Form

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

4. Using Point-Slope Form1 2 4 3 5 -1 -2 -3 -4 -5
(2,2)
Plug it into the point-slope form
Rewrite in Slope-Int Form
We need the slope and a point:

5. Write the Equation in Point-Slope Form
Step 1: Plug it in

6. A Challenge
Can you write the equation of a line in point-slope form that passes through (-3,6) and (1,-2)
