Which of the following are perpendicular to the line y=-1/3x+5 (three answers)

3x-y=2

y=3x

3x+y=5

1/3x-y=3

3x-y=6

Y = - 1/3x + 5 ... slope here is - 1/3. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So ur perpendicular line will have a slope of 3.

y = 3x ... has a slope of 3, so this is perpendicular.

3x - y = 2 ... y = 3x - 2 ... has a slope of 3 and is therefore perpendicular

3x - y = 6 ... y = 3x - 6 ... has a slope of 3 and is perpendicular
