4.2 Point-Slope Form

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

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

Using Point-Slope Form 1 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:

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

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