=**Do Now**= 1) 2x + y = 3
 * Write each equation in slope intercept form. y = mx + b Solve for y and state the slope and y intercept.**

2) 4x - y = 7

3) y = 2x + 2
 * Graph the following lines by using the y intercept first and then the slope.**

4) y = (3/5)x -2

=What is point slope form?= Point slope form is a way of writing a linear equation when you know a point on a line and how steep the line is.

=**Learning Objectives**=
 * 1) Write an equation in point slope form when given a point and the slope of a line.
 * 2) Find the slope of a line and write an equation in point slope form when given two points.
 * 3) Write an equation in slope intercept form when given two points.
 * 4) Graph lines using equations in point slope form.

=Lesson Notes=

= Point Slope Form =


 * y - y1 = m(x - x1)**

This linear equation is best when you know both a point and a slope of a line. For example if:


 * Point** = (4,3) and **Slope** = 1/2, we write the equation like this

y - 3 = 1/2(x - 4)

The 4 and the 3 are from the point and the 1/2 is from the slope.

Things to remember about Point Slope Form.

 * 1) The letter m represents slope.
 * 2) The y1 and the x1 are the numbers from a point.
 * 3) The x and y are variables.

=Power Point= The following presentation gives examples of writing equations in slope intercept form given two points. In order to write an equation in slope intercept form with only two points you need to take the following steps:


 * 1) Find the slope. If you forgot how, look at your notes on slope.
 * 2) Write an equation in point slope form using the first of the two points
 * 3) Distribute the slope through the parenthesis.
 * 4) Get y by itself.
