Point-Slope Form (given a point and slope)
TSWBAT: write an equation given a point and the slope using the Point-Slope formula.
Students verify that a point lies on a line, given an equation of the line. Students are able to derive linear equations by using the point-slope formula.

4. Notes
Graph the line with the given slope that contains the given point. Find the y-intercept and then write the equation of the line.
Ex. 4

5. Notes
Now you try.
Graph the line with the given slope that contains the given point. Find the y-intercept and then write the equation of the line.
Ex. 5

6. Before we were given the graph, and told to find the equation.
Notes
Point-Slope Form
It’s called the Point-Slope Formula because you need a point and the slope to write the equation of the line.
Before we were given the graph, and told to find the equation.
Now we will be given a point and the slope, and told to find the equation.
