Algebra 1 - Equations for Perpendicular Lines
This post explains and give practice opportunities related to TEKS A.2F:
write the equation of a line that contains a given point and is perpendicular to a given line;
Lines that are perpendicular have opposite reciprocal slopes. Students learn to graph a perpendicular line given a point and the equation for the other line.
