5.6 Intro to Parallel and Perpendicular Lines

Parallel Lines:  SAME SLOPE,  different y intercepts
Perpendicular Lines:  SLOPES ARE OPPOSITE RECIPROCALS, any y intercepts

Opposite reciprocal -  change the sign and flip the number

5.5 Standard Form To Slope-Intercept Form.mov

To put an equation into slope intercept form:
Keep in mind your goal is to isolate the variable y.
1.  move your x term over by adding or subtracting it
2.  divide to isolate the variable y

5.4 How to Write Linear Equations Given Two Points eHow com

to write an equation when given 2 points:

Step #1  Find the slope by using the formula   y2 - y1 /  x2 - x1
Step #2   Find your y int by plugging in a point and your slope to y = mx + b.  then solve that equation for b.
