Question

Find the equation of the line passing though the origin and perpendicular to the line y=-3x

Answer 1

y=x/3

the perpendicular line has a slope that's the negative inverse

take -3, change the sign and flip the fraction upside down

change -3/1 to +1/3

Answer 2

y=x/3

the perpendicular line has a slope that's the negative inverse

take -3, change the sign and flip the fraction upside down

change -3/1 to +1/3
