Buzz graphed the following two lines. One line has equation y=-6x+2. Which of the following is an equation of the other line?

• x+y=-3
• x+y=3
• 3x+3y=3

When you graph the exact same equation twice,

• you will have no solution. 
• you will have one solution.
• you will have infinite solutions. 
• you will graph a giraffe.
