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 and point B be . The given ratio is .
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 and coordinates of the dividing point.
Step 3: Substitute Values into Formula
Now, we substitute the values of and into the section formula. This will give us the expressions for the and coordinates of the dividing point.
Step 4: Calculate Coordinates
Finally, we perform the arithmetic operations to calculate the exact values of and . This gives us the coordinates of the point that divides the line segment.
