Answer the following question:
Find the value of k the point P(1, k) lies on the line passing through the points A(2, 2) and B(3, 3)
उत्तर
Since P(1, k) lies on the line passing through the points A(2, 2) and B(3, 3), the points P, A, B are collinear.
∴ slope of AP = slope of AB
∴ `("k" - 2)/(1 - 2) = (3 - 2)/(3 - 2)`
∴ `("k" - 2)/(-1) = 1/1` = 1
∴ k – 2 = –1
∴ k = 1
