At a restaurant jars of tomato sauce are stored in boxes in the pantry. Each box contains 8 jars of tomato sauce. A cook uses 2 jars from 1 of the boxes.

Which function shows the relationship between y, the total number of jars of tomato sauce remaining in the pantry, and x, the number of boxes in the pantry?

• y = 8x + 6

• y = 8x

• y = 8x - 2

• y = 6x

Which expression is equivalent to the expression -28x² + 35x?

• 7x(4x + 5)

• -7x(4x - 5)

• 7x(4x -5)
