SECTION 2 Everything Linear
I. Slope of a Line The formula for slope is Draw examples of Positive, Negative, 0 and Undefined Slopes
Ex 1: Write the equation of the line. A. m = 3; (1, 5) B. (-10, 3) and (-2, -5)
III. Parallel & Perpendicular Lines Parallel Lines have ________ slopes. Perpendicular lines have slopes that are ________ ___________.
EXAMPLE 2 • Find the point-slope forms of the equations of the lines that pass through (2, -1) and are • A. Parallel to 2x – 3y = 5 • B. Perpendicular to 2x – 3y = 5
Example 3 Using the answers in example 2, change the equations in part A and B into standard form. A. or B.
