Chapter 6: Section 4 Point-Slope Form
The formula Point-Slope Form The point: (x 1, y 1 ) Slope: m
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)
Write the equations of the following lines in point-slope form 1. point: (3, 4); m = point: (-2, 0); m = -2/5 3. point: (0, 4); m = 1
Put the previous three linear equations into slope-intercept form
Can you get point slope from just two points? 1. (2, 3) and (1, 5) 2. (-4, 1) and (0, 6)
