Question

Which equation represents a line that is perpendicular to y=3x−4?

Answer 1

• - 1/3x + 2

Explanation:

Given line:

• y = 3x - 4

Perpendicular lines have negative-reciprocal slopes:

• m₁*m₂ = - 1

Since m₁ = 3, we can find m₂:

• 3*m₂ = - 1
• m₂ = - 1/3

Given choices:

• -1/3x + 2 or 1/3x - 4

Correct choice is the first one
