Warmups Graph y = -3 Graph y = 2x - 4 Write an equation in standard form: (2,-2) (1,4) Parallel, Perpendicular or neither?

Objective: To write an equation of a line perpendicular to another Perpendicular Lines Objective: To write an equation of a line perpendicular to another

Perpendicular Lines How will yesterday change if we want the lines to be perpendicular?? The slope will be opposite sign & reciprocal!!!! Write an equation in slope-intercept form that passes through the given point and is perpendicular to the given line. Example 1: (0,4)

Example 2 Write an equation in SLOPE-INTERCEPT form that passes through the given point and is perpendicular to the given line. y = 2x - 5 (6,4)

Example 3 Write an equation in SLOPE-INTERCEPT form that passes through the given point and is perpendicular to the given line. 2x – 3y = 9 (0,2)

TOO 5x + 4y = 8 (10,5) y = 1/4x – 4 (-2,3) 14x + 2y = 4 (6,4)
