## Algebra 1: Common Core (15th Edition)

You have the equations: y=4x-2 and -x+4y=0. The slope for the first equation is 4. Put the second equation into slope-intercept form to find its slope: -x+4y=0 -add x to both sides- 4y=x+0 -divide both sides by 4- y=$\frac{1}{4}$x The slopes are not the same so the lines are not parallel and they are not negative reciprocals so they are not perpendicular. They are neither parallel or perpendicular.
