Scribe Post 11/8/10

In class today we went over homework and we also talked about equations. Today we talked about how the point on the X axis is a vertical line and a vertical line has an undefined slope. X is undefined because its a vertical line and anything you cant walk on without falling has an undefined slope.
Ex: x=2







Also we learned that the point on the y axis has a slope of zero.
Ex: y=2














Today we also learned that parallel lines have the same slope and that perpendicular lines have a slopes that are negative reciprocal of each other.

here are some equations that might help you find certain forms:
y-y1 =m(x-x1) is point slope form.
Ax + By = C and thats standard form.
Y= Mx + B is slope intercept form
