WebGiven, point P (9a - 2, -b) divides the line segments joining A (3a + 1, -3) and B (8a, 5) in the ratio 3:1 We have to find the values of a and b. The coordinates of the point P which divides the line segment joining the points A (x₁ , y₁) and B (x₂ , y₂) internally in the ratio m₁ : m₂ are [ (m₁x₂ + m₂x₁)/ (m₁ + m₂) , (m₁y₂ + m₂y₁)/ (m₁ + m₂)] WebIf P (9a – 2, -b) divides the line segment joining A (3a + 1, -3) and B (8a, 5) in the ratio 3 : 1, find the values of a and b. Answer: Solution: The coordinates of the point that splits a line segment (internally or externally) into a specific ratio are found using the Section formula.

To do: We have to find the values of $a$ and $b$. Solution: Using the division formula, $( x,\ y)=( \frac{mx_2+nx_1}{m+n},\ \frac{my_2+ny_1}{m+n})$ Here, $x_1=3a+1,\ y_1=-3,\ x_2=8a,\ y_2=5,\ x=9a-2,\ y=-b, \ m=3$ and $n=1$.

Thus, the coordinates of Q are shown as (iii) Assume P and Q are the points of the trisection of AB . i.e., AP = PQ = OQ. As, P divides AB within in the ratio 1 : 2. Thus, the coordinates of P, by putting in the Section Formula, are shown as. After this, Q also divides AB putting in the ration 2 : 1.
WebThe section formula tells us the coordinates of the point which divides a given line segment into two parts such that their lengths are in the ratio m:n m: n. The midpoint of a line segment is the point that divides a line segment in two equal halves. The section formula builds on it and is a more powerful tool; it locates the point dividing ...
