Writing the Equation of a Line
by Chris Courteau
1. From a point and slope
1.1. Use the equation to find the y-intercept
1.2. Put the slope and intercept into the equation
2. Equations are written in slope-intercept form
3. Slope is known as the rate of change. It is the change in the independent variable over the dependent variable
4. The Y-intercept is also known as the initial condition
5. From a graph
5.1. Find where the grpah hits the Y axis
5.2. Calculate the rate of change(slope)
5.3. Put it altogether
6. From two points
6.1. First find slope
6.2. Find the Y intercept
6.3. Write the equation in slope intercept form
