The correct Answer is:
To find the coordinates of the centroid \( G \) of the triangle with vertices \( A(-1, 3) \), \( B(4, 2) \), and \( C(3, -2) \), we can use the formula for the centroid of a triangle. The coordinates of the centroid \( G(x, y) \) are given by: \[ G_x = \frac{x_1 + x_2 + x_3}{3} \] \[ G_y = \frac{y_1 + y_2 + y_3}{3} \] where \( (x_1, y_1) \), \( (x_2, y_2) \), and \( (x_3, y_3) \) are the coordinates of the vertices \( A \), \( B \), and \( C \). ### Step 1: Identify the coordinates of the vertices The coordinates of the vertices are: - \( A(-1, 3) \) - \( B(4, 2) \) - \( C(3, -2) \) ### Step 2: Calculate the x-coordinate of the centroid Using the formula for \( G_x \): \[ G_x = \frac{x_A + x_B + x_C}{3} = \frac{-1 + 4 + 3}{3} \] Calculating the sum: \[ G_x = \frac{6}{3} = 2 \] ### Step 3: Calculate the y-coordinate of the centroid Using the formula for \( G_y \): \[ G_y = \frac{y_A + y_B + y_C}{3} = \frac{3 + 2 - 2}{3} \] Calculating the sum: \[ G_y = \frac{3}{3} = 1 \] ### Step 4: Write the coordinates of the centroid Thus, the coordinates of the centroid \( G \) are: \[ G(2, 1) \] ### Final Answer: The coordinates of the centroid \( G \) of the triangle are \( (2, 1) \).
