The slope of the first equation is
. They are neither equal nor
4-4 Parallel and Perpendicular Lines
opposite reciprocals, so the graphs of the equations are neither parallel nor perpendicular.
2x + 7y = 35
4x + 14y = 42
Write the equations in slope-intercept form.
The slope of the both equations is
so the graphs of the equations are parallel.
Write an equation of the line that is parallel to the graph of y = 7x
3 and passes through the origin.
The slope of the line with equation y = 7x
3 is 7. The line parallel to y = 7x
3 has the same slope, 7. The origin is
the point (0, 0).
Scientists excavating a dinosaur mapped the site on a coordinate plane. If one bone lies from ( 5,
8) to (10, 1) and a second bone lies from ( 10, 3) to ( 5, 6), are the bones parallel? Explain.
