To solve the problem of finding the ratio in which the line joining the points \( A(1, 1) \) and \( B(5, 7) \) is divided by the line \( x + y = 4 \), we can follow these steps: ### Step 1: Identify the Points and the Line Let \( A(1, 1) \) and \( B(5, 7) \) be the points. The line \( x + y = 4 \) will intersect the line segment \( AB \) at some point \( M \). ### Step 2: Use the Section Formula Assume that point \( M \) divides the line segment \( AB \) in the ratio \( \lambda : 1 \). According to the section formula, the coordinates of point \( M \) can be expressed as: ...
