| Slope | The M in Y=MX+B |
| X-intercept | The point where the line intersects the X axis. |
| X-intercept | Set Y=0 and solve for X |
| Y-intercept | The B in Y=MX+B |
| Y-intercept | where the line intersects the Y axis. |
| Pathagorean Theorem | a^2 + b^2 = c^2 |
| Slope | (x2-x1)/(y2-y1) |
| To find the equation of a line, use | (Y-y1)m(X-x1) |
| Distribution property | 6(x-2)=6x-12 |
| scattered points going up from left to right | positive correlation (scatterplot) |
| scattered points going down from left to right | negative correlation (scatterplot) |
| points scattered in no particular pattern | no correlation (scatterplot) |
| negative slope | m = -6 |
| positive slope | m = 6 |
