The correct Answer is:
To find the point of intersection of the medians of a triangle (the centroid), we can use the formula for the centroid given the vertices of the triangle. ### Step-by-Step Solution: 1. **Identify the vertices of the triangle:** The vertices of the triangle are given as: - \( A(-1, 0) \) - \( B(5, -2) \) - \( C(8, 2) \) 2. **Use the centroid formula:** The formula for the centroid \( G \) of a triangle with vertices \( (x_1, y_1) \), \( (x_2, y_2) \), and \( (x_3, y_3) \) is: \[ G\left( \frac{x_1 + x_2 + x_3}{3}, \frac{y_1 + y_2 + y_3}{3} \right) \] 3. **Substitute the coordinates into the formula:** Here, substituting the coordinates of the vertices into the formula: - \( x_1 = -1 \), \( y_1 = 0 \) - \( x_2 = 5 \), \( y_2 = -2 \) - \( x_3 = 8 \), \( y_3 = 2 \) The x-coordinate of the centroid \( G_x \) is calculated as: \[ G_x = \frac{-1 + 5 + 8}{3} \] The y-coordinate of the centroid \( G_y \) is calculated as: \[ G_y = \frac{0 - 2 + 2}{3} \] 4. **Calculate the x-coordinate:** \[ G_x = \frac{-1 + 5 + 8}{3} = \frac{12}{3} = 4 \] 5. **Calculate the y-coordinate:** \[ G_y = \frac{0 - 2 + 2}{3} = \frac{0}{3} = 0 \] 6. **Combine the coordinates to find the centroid:** Thus, the point of intersection of the medians, or the centroid \( G \), is: \[ G(4, 0) \] ### Final Answer: The point of intersection of the medians of the triangle is \( (4, 0) \).
