Heading 11/5/2019 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.
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.
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.
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.
Notes Now you try. Write the equation of the line. Ex. Ex. Label your points. Write this every time. Plug in the values. Distribute. Get y by itself.
