A.4.0 B.7.5 C.8.0 D.8.5 E.15.0 Correct Answer: B Here's Why: Figures in a Coordinate Plane The figure provides all the information you need to answer the question. What Is the Question Asking? You are asked to figure out the area of a triangle that is defined by the points in a coordinate plane. What Do You Know? The triangle in the figure is a right triangle with the right angle at the lower left. Because it is a right triangle, its base and height are the two sides that form the right angle. The area of a triangle is bh. The base of the triangle extends from point (0, 0) to point (5, 0). So it is 5 units long. The height of the triangle extends from point (0, 0) to point (0, 3). So it is 3 units long. Area = bh = (3)(5) = (15) = 7.5 Difficulty: Medium Question Type: Standard Multiple Choice
