about data Evaluate positive/negative correlation of

data Calculate midpoint:

TEST TOPICS Solve linear equations Write linear equations based on application

problems Write linear equations involving

supplements and complements Write median equation (passes through

triangle vertex and mdpt of opposite side) Write equation of perpendicular bisector of

side (passes through midpoint; perpendicular to slope of side)

Write equation of altitude of triangle (passes through vertex; slope perpendicular to base)

TEST TOPICS Solve systems using substitution Solve systems using elimination Find intersection point of medians

(centroid), altitudes (orthocenter), perpendicular bisectors (circumcenter)

Solve systems of three variables Write equation of parabola using a

system of three variables.
