Question

Which of the following equations represents a perpendicular line to 6x - 2y = 20?

Answer 1

help :(

Answer 2

you do not have provided the options
just to let you know that if the lines are perpendicular then their slopes are
if two perpendicular lines have slopes m1 and m2 then
\[\Large m_{1}m_{2}=-1\]
slope of then given line is m1=3
so slope of line perpendicular will be m2
\[\Large m_{2}=\frac{-1}{m_{1}}=\frac{-1}{3}\]
look in your options for the line whose slope is -1/3 that will be perpendicular to the given line!
