Algebra Lesson 2.6: Point-Slope Form

Practice Exercises

Write the equation of the line with the given point and slope in point-slope form. Then rewrite the equation in slope-intercept form:

1. $(x_1,y_1) = (2,3)$ and $m=2$

2. $(x_1,y_1) = (-1,4)$ and $m = \frac{1}{2}$

3. $(x_1,y_1) = (4,0)$ and $m = 0$

4. $(x_1,y_1) = (0,-1)$ and $m = -5$
