Trying to do my review for midterms and i cant find my notes for these formulas. I just need to know what they are. Oh and if you know of some good sites with algebra II help that would be cool.

point slope- y-ysub1=m(x-xsub1)
slope intercept- y-mx+b
standard form- Ax +By=C

Standard form: Ax+By+C=0 ( Ax+By=C is also "standard," just watch the sign on C)
Slope-intercept: y=mx+b where m is the slope of the line and b is the y-intercept
Point-slope: y-ysub1=m(x-xsub1) where m is the slope and ysub1 and xsub1 are the coordinates of a known point on the line

There are no e's in standard katybug. we should leave eulers number and natural logarithms for another day. Tell ya what I got my notes from college algebra and we covered that stuff I'll have to get back to ya though.
slope = rise over run
slope = y/x
they might have used m as the letter to represent slope.

y=mx+c
m=gradient = (y2-y1)/(x2-x1)
c=intercept
(y-y1)=m(x-x1)
standard form is a way of writing a number e.g. 5.4*10^6
the number before the * must be 1 or higher but less than 10. You always write 10^ (an whole number)
more egs
3*10^4
1*10^8
9.99999*10^3
