What is the slope of a line perpendicular to the line whose equation is 6x+y=66x+y=6. fully reduce your answer?
shepuryov [24]
It looks like your equation repeated twice. I'm assuming it's 6x + y = 6.

I'm going to put your equation into slope-intercept form: y = - 6x + 6.

For the slope to be perpendicular, we do the opposite reciprocal of the slope given. So your slope of a perpendicular line is 1/6.
