The point A(-6, 3) is reflected over the origin and its image is point B. What are
the coordinates of point B?

  B(6, -3)

Step-by-step explanation:

Reflection over the origin changes the signs of the coordinates.

  (x, y) ⇒ (-x, -y) . . . . reflection over the origin

  A(-6, 3) ⇒ B(6, -3)

Additional comment

Reflection over the origin is fully equivalent to rotation 180° about the origin, or reflection over both the x- and y-axes (in any order).

ANSWER: B. 13/8

STEP BY STEP THING:

20a−16=12(3−a)

20a−16=−12a+36

32a−16=36

32a=52

32a/32 = 52/32

a = 13/8
