Equations From Lines
Objectives:
Students will determine equations in point-slope, standard, and slope-intercept form given 2 points on a line or 1 point on a line and its slope.
NCTM Standards:
Students understand relations and functions and select, convert flexibly among, and use various representations for them.
California Content Standards:
(7.0) Students verify that a point lies on a line, given an equation of the line. Students are able to derive linear equations by using the point-slope formula.
(8.0) Students are able to find the equation of a line perpendicular to a given line that passes through a given point.

Help
In college in the 1960's I discovered that I have a knack for helping people understand technical ideas, and I have used this talent ever since in many contexts, from modeling biological systems using mathematics, to doing research and development in the telecommunications software industry, to tutoring kids and adults in math, to teaching math part-time at several high schools.
