Question

Question 11 (Multiple Choice Worth 1 points) (05.05 MC) The length of a rectangle is shown below: On a coordinate grid from negative 6 to positive 6 on the x-axis and on the y-axis, two points A and B are shown. The point A is on ordered pair negative 2, 3, and the point B is on ordered pair 3, 3. If the area of the rectangle to be drawn is 30 square units, where should points C and D be located, if they lie vertically below A and B, to make this rectangle? C(3, −2), D(−2, −2) C(3, −3), D(−2, −3) C(−3, 3), D(−3, −2) C(−2, 3), D(−2, −2)

Answer 1

C(3, −3), D(−2, −3)

Explanation:

Answer 2

C(3, −3), D(−2, −3)

Explanation:

The given segment is 5 units long. (You can subtract the coordinates or count the grid squares to see this.)

In order for the area to be 30 square units, the product of length and width must be 30.

30 = 5×width

30/5 = width = 6

The horizontal line that is 6 units below the one shown is at y = -3. That is, the coordinates of C and D will have y-values of -3. Only one answer choice matches.
