Answer

The quadrilateral \( ABCD \) with vertices \( A(-3,4) \), \( B(4,5) \), \( C(5,-1) \), and \( D(-2,-2) \) is a parallelogram because both pairs of opposite sides are parallel.

Beyond the Answer

To graph the quadrilateral with vertices A(-3,4), B(4,5), C(5,-1), and D(-2,-2), plot each point on a coordinate plane and connect them in order. You'll see a figure that resembles a skewed quadrilateral! Using the slope formula \( m = \frac{y_2 - y_1}{x_2 - x_1} \), find the slopes of segments AB, BC, CD, and DA to determine if opposite sides are parallel. Upon calculating the slopes: - Slope AB = \( \frac{5-4}{4-(-3)} = \frac{1}{7} \) - Slope BC = \( \frac{-1-5}{5-4} = -6 \) - Slope CD = \( \frac{-2-(-1)}{-2-5} = \frac{-1}{-7} = \frac{1}{7} \) - Slope DA = \( \frac{4-(-2)}{-3-(-2)} = \frac{6}{-1} = -6 \) Since the slopes of AB and CD are equal (\(\frac{1}{7}\)) and the slopes of BC and DA are equal (-6), you can conclude that the figure is a parallelogram because both pairs of opposite sides have equal slopes, which confirms they are parallel.
