Rita is building a picture frame for her mom for Mother's day. She is sketching the layout on a piece of graph paper where the top and the bottom frame can be represented by the equations y = 2 and y = 6.
Choose the set of equations that would represent the sides of frame, assuming they will be perpendicular to the top and bottom of the frame.

Evaluate the expression for the given value of the variable. | ? 4 b ? 8 | + ? ? ? 1 ? b 2 ? ? + 2 b 3 -4b-8+-1-b2+2b3 ; b = ? 2 b=-2
