Document Summary

Math 112 lecture 8 2. 1 parallel and perpendicular lines. Parallel line: two lines with slop m1 and m2 neither of which is vertical, are parallel if and only if their. 09/06/16 slopes are equal i. e. m1 = m2. Perpendicular line: two lines with nonzero slopes m1 and m2 are perpendicular if and only if their slopes have a product of -1 i. e. m1 x m2 = -1. 6m2 = -1 m2 = - y = - Math 112 lecture 9 2. 2 linear equations. Linear equation: an equation is a statement that two mathematical expressions are equal. E. g. x + 5 = 9 + 3x xy + x2 = y2 + x. Linear equation is one variable: a linear equation in one variable in an equation that can be written in the form ax + b = 0. Where a and b are constants with a 0. Ex: solve the following equations: 3x + 4 = 9.
