4-4 Parallel and Perpendicular Lines
Write an equation in slope-intercept form for the line that passes through the given point and is parallel
to the graph of the given equation.
( 1, 2),
The slope of the line with equation
is . The line parallel to
has the same slope, .
(0, 4), y = 4x + 5
The slope of the line with equation y = 4x + 5 is 4. The line parallel to y = 4x + 5 has the same slope, 4.
A garden is in the shape of a quadrilateral with vertices A( 2, 1), B(3, 3), C(5, 7), and D( 3, 4). Two
paths represented by
cut across the garden. Are the paths perpendicular? Explain.
