Question

Find the slope of a line that is a) parallel and b) perpendicular to the given line: 9x+y=2

Answer 1

a is 9
b is 1/9

Answer 2

How did you figure it out?

Answer 3

put a negitive sign infront of both of those, but you change it to slope intersect form and a parrel line has the same slope and perpendicular has the reciplical.

Answer 4

Ok. Thank you.

Answer 5

9x+y=2
->y = -9x + 2
=> Parallel line's slope: m = -9
=> Perpendicular's slope m = 1/9
