Question

18. What is an equation of the line that passes through the point (3, -1) and is perpendicular to the equation

y = -3x + 2?
A. y = -3x + 8
B. y = -3x
C. y = 1/3x
D. y = 1/3x - 2

CAN SOMEONE PLEASE SHOW ME HOW TO SLOVE THIS

Answer 1

• D. y = 1/3x - 2

Explanation:

It mentions the new line is perpendicular to the original line.

• New slope = -(1/-3) = 1/3

It also mentions it passes through the point (3, -1).

Using point-slope form of equation,

• y + 1 = 1/3(x - 3)
• y + 1 = 1/3x - 1
• y = 1/3x - 2

Answer 2

It’s D
