Find the coordinates of the point dividing the line segment joining A(3, 5) and B(9, 11) internally in the ratio 2 : 1.

Answer: The coordinates of the point dividing the line segment are (7, 9).

Step-by-step solution

Step 1: Identify Given Information

First, we identify the given coordinates of the two points, A and B, and the ratio in which the line segment AB is divided. Let the coordinates of point A be (x1,y1)(x_1, y_1) and point B be (x2,y2)(x_2, y_2). The given ratio is m1:m2=2:1m_1 : m_2 = 2 : 1.

Step 2: Recall Section Formula

To find the coordinates of a point that divides a line segment internally in a given ratio, we use the section formula. This formula helps us calculate the xx and yy coordinates of the dividing point.

Step 3: Substitute Values into Formula

Now, we substitute the values of x1,y1,x2,y2,m1,x_1, y_1, x_2, y_2, m_1, and m2m_2 into the section formula. This will give us the expressions for the xx and yy coordinates of the dividing point.

Step 4: Calculate Coordinates

Finally, we perform the arithmetic operations to calculate the exact values of xx and yy. This gives us the coordinates of the point that divides the line segment.
