1. Chapter 6: Section 4
Point-Slope Form

2. The formula
Point-Slope Form
Slope: m
The point: (x1, y1)

3. Use it When should we use this formula?
When you have a point and the slope!
Write the equation of the line that has a slope, m = 3/4, and goes through the point, (2, -1)

4. Write the equations of the following lines in point-slope form
point: (3, 4); m = -3
point: (-2, 0); m = -2/5
point: (0, 4); m = 1

5. Put the previous three linear equations into slope-intercept form.

6. Can you get point slope from just two points?
(2, 3) and (1, 5)
(-4, 1) and (0, 6)
