the formula for slope is rise over run.
slope=rise/run.
just substitute it to the given.
where rise is x and run is y.
Find the slope of 8x+4y=7 in parallel and perpendicular lines. Please help me figure this out?

Natalie, use the method I showed you in your previous post
slope of lines parallel to 8x + 4y = 7 = -8/7
slope of perpendicular lines = + 7/8
slope of lines parallel to 8x + 4y = 7 = -8/7
slope of perpendicular lines = + 7/8
