Question 25

Coordinate Geometry

The lines 2y + 3x − 16 = 0 and 7y − 2x − 6 = 0 intersect at point P. Find the coordinates of P.

  1. A.(4, 2)
  2. B.(4, −2)
  3. C.(−4, 2)
  4. D.(−4, −2)
Show the answer and explanation

Answer: A ((4, 2))

Explanation

3x + 2y = 16 and −2x + 7y = 6 give y = 2 and x = 4.
