x intercept | let y=0 |
y intercept | let x=0 |
slope | steepness of a line. |
m=^y/^x | vertical/horizontal |
m=? (.,.)(.,.) | y=y2-y1/x2-x1 |
special lines: x=? | undefined |
special lines:y=? | m=o |
slope-intercept form | y=mx+b |
parallel | same slope. m1=m2 |
perpindicular | intersect at 90 degress. opposite in sign, reciprocal |
point slope | y-y1=m(x-x1) |
