4-4 Parallel and Perpendicular Lines
graphs of the equations are perpendicular.
3x + 4y = 8
4x + 3y = 6
Write the equations in slope-intercept form.
The slope of the first equation is
. They are neither equal nor opposite
reciprocals, so the graphs of the equations are neither parallel nor perpendicular.
2x + 5y = 15
3x + 5y = 15
Write the equations in slope-intercept form.
