Find the equation perpendicular to 2x - y = 4 and pass through (2, 4):

  • A
    2x + y - 10 = 0
  • B
    x + 2y + 10 = 0
  • C
    x + 2y - 10 = 0
  • D
    x + y - 10 = 0
✓

Answer

  1. x + 2y - 10 = 0

Solution:

Line 2x - y = 4 has slope 2. Line perpendicular to given line has slope $\frac{-1}{2}$

equation is $(\text{y}-4) = \big(\frac{-1}{2}\big) (\text{x}-2)$

2y - 8 = -x + 2

⇒ x + 2y - 10 = 0
