- 1SymmetrySymmetrical wrt:
1. X-axis if equation is unchanged when y is replaced with -y
2. Y-axis if equation is unchanged when x is replaced with -x
3. Origin if equation is unchanged when x and y are replaced by -x and -y - 2Slope-rise/run=m
-measures rate of change from (x1,y1) to (x2,y2)
-m=(y2-y1)/(x2-x1) - 3Equations of a Line1. Point-Slope Form: y-y1=m(x-x1)
2. Slope-Intercept Form: y=mx+b (b=y-int)
3. Standard Form: ax+by=c (a,b=/=0) - 4Parallel and Perpendicular Lines-2 lines are parallel if they have the same slope
-2 lines are perpendicular if their slopes are negative reciprocals of each other (m2=-1/m1)
