The correct Answer is:
To solve the problem of finding the ratio in which the line joining the points (-4, 3) and (5, -2) is divided by the x-axis and the y-axis, we will follow these steps: ### Step 1: Finding the ratio for the x-axis 1. **Identify the coordinates**: The points are A(-4, 3) and B(5, -2). 2. **Set the y-coordinate to 0**: Since we are finding where the line intersects the x-axis, we set y = 0. 3. **Use the section formula**: The section formula states that if a point P divides the line segment joining points A(x1, y1) and B(x2, y2) in the ratio m1:m2, then: \[ y = \frac{m2 \cdot y1 + m1 \cdot y2}{m1 + m2} \] Here, we let the ratio be k:1 (where m1 = k and m2 = 1). 4. **Substituting the values**: \[ 0 = \frac{1 \cdot 3 + k \cdot (-2)}{k + 1} \] This simplifies to: \[ 0 = 3 - 2k \] Rearranging gives: \[ 2k = 3 \quad \Rightarrow \quad k = \frac{3}{2} \] 5. **Expressing the ratio**: Thus, the ratio in which the line joins the points (-4, 3) and (5, -2) is divided by the x-axis is: \[ 3:2 \] ### Step 2: Finding the ratio for the y-axis 1. **Set the x-coordinate to 0**: Since we are finding where the line intersects the y-axis, we set x = 0. 2. **Using the section formula again**: The formula for the x-coordinate is: \[ x = \frac{m2 \cdot x1 + m1 \cdot x2}{m1 + m2} \] Here, we let the ratio be k:1 (where m1 = k and m2 = 1). 3. **Substituting the values**: \[ 0 = \frac{1 \cdot (-4) + k \cdot 5}{k + 1} \] This simplifies to: \[ 0 = -4 + 5k \] Rearranging gives: \[ 5k = 4 \quad \Rightarrow \quad k = \frac{4}{5} \] 4. **Expressing the ratio**: Thus, the ratio in which the line joins the points (-4, 3) and (5, -2) is divided by the y-axis is: \[ 4:5 \] ### Final Result The ratios are: - For the x-axis: **3:2** - For the y-axis: **4:5** ### Conclusion Since the answer is not listed in the options provided, the correct choice is: **(d) None of these.** ---
