Question 15 (request help)
On a coordinate plane, draw triangle ABC with vertices A(−1, −1), B(3, −1), and C(−1, 2). Find the area of the triangle in square units.

Question 16 (request help)
The points (4, 3) and (−4, 0) are graphed on a coordinate plane. The point (4, 3) is reflected across the x- and y-axes. If all four points are connected, what figure is graphed?

Question 18 (request help)
When a point is reflected across the y-axis, the new point has a negative x-coordinate.

Question 19 (request help)
The point (x, y) is reflected across the x-axis. Then the new point is reflected across the y-axis. The location of the point after both reflections is (-x, -y).

Question 20 (request help)
The x-coordinate of a point that lies on the y-axis is positive.
