3. What we Know so far…. Slope Intercept Form
Where m is the slope and b is the intercept
Standard Form
Where A, B & C are just numbers

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

5. 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:
