| Distance | √(x-x)^2+(y-y)^2 |
| Midpoint | (x+X)/2 , (y+y)/2 |
| Slope | y-y/x-x |
| Slope-Intercept | y=mx+b |
| Point-Slope | (y-y)=m(x-x) |
| Standard Form | Ax+By=C |
| Perimeter | add all sides |
| Area of a Triangle | A=1/2bh |
| Area of a Square | A=LW |
| Quadratic Equation | -b+√b^2-4ab/2a |
| Direct Variation | y=kx |
| Rule for Multiplying Monomials | ADD the exponets - b^2 x b^ = b^6 |
| Rule for Dividing Monomials | SUBTRACT the exponets - 4x^7/2x^3 = 2x^4/1 |
| Rule for Power to a Power | MULTIPLY the exponets - (2x^4)^3 = (2)^3(x^4)^3 |
| Rule for negative exponets (unhappy!) | move them to the opposite side of the fraction bar - b^-4 = 1/b^4 |
