Find the gradient of the line passing through the points P(1, 1) and Q(2, 5).

Find the gradient of the line passing through the points P(1, 1) and Q(2, 5).
  • A.
    3
  • B.
    2
  • C.
    5
  • D.
    4
Correct Answer: Option D
Explanation

Let (x1, y1) = (1, 1) and (x2, y2)= (2, 5)
then gradient m of (bar{PQ}) is
m = (frac{y_2 – y_1}{x_2 – x_1}) = (frac{5 – 1}{2 – 1})
= (frac{4}{1})
= 4
