Write an equation in standard form for the line that is parallel to the graph of –8x = 5 – 4y and has y-intercept –0.5.

• x – 0.5y = 0.25
• 10x – 5y = 2.5
• 4x – 2y = 1

• -6
• undefined
• 0

The graphs of which pair of lines are perpendicular?

• 2x – 3y = 12, y = – 2/3x + 5
• 3x + 2y = 6, 2x – 3y = 7
• y = 4x + 13, y = 1/4x – 13
• x + y = 1, 2y = –2x + 2
