BTW heard u sucked at algebra...
x = [-b ± sqr(b² - 4ac)]/2a
^ Only works for quadratic fuctions in the form y = ax² + bx + c
y - y1 = b(x - x1) is Point Slope Form, assuming that the values of y, b, and x are the same as they are in Slope Intercept form ( y = mx + b ).
You also might want to google about factoring cubic and quarticn functions, assuming you already know quadratics. Also google multiplying matrices... that will make your life easier, too.
Also, is this course you're taking just algebra or does it have Geometry in it, too? When I took Algebra 3 or 4 years ago, it also included half of Geometry and Trig. If you need help on any of that stuff, let me know. ^_^
