Question

(05.05)On the coordinate plane below, what is the length of AB?

A coordinate plane is shown with the following points A at negative 9, 4; B at 5, 4; C at 5, negative 5; D at negative 9, negative 5. All points are connected to create a rectangle.

8 units
9 units
14 units
15 units

Answer 1

14 units

Explanation:

both points have the same y-coordinate, so therefore, the line is horizontal from x = -9 and x = 5 9 (plus I did the 5.05 math quiz segment two 6th grade)

Answer 2

Point A(-9, 4) and point B(5, 4)

Notice that the two points have the same y-coordinate and this means, the line is horizontal from x = -9 and x = 5

Hence the length of AB is 14 units
