Parallel Lines never intersect because...

• they have the same slopes. 
• they have the same y-intercept.
• they have different slopes.
• they have different y-intercepts.

Nancy went to the grocery story. On Monday she purchased 4 apples and 6 bananas for a total of $13. On Wednesday she purchased 3 apples and 7 bananas for a total of $13.50. Which system of equations represents the situation?

• 4A + 6B = 3

  13.5A - 13B = 6

• A + B = 4

  A - B = 6

• 4A + 6B = 13

  3A + 7B = 13.5

• 4A - 6B = 13

  3A - 7B = 13.5

Is (5, 3) is a solution of the system:
2x -y = 7
x + y = 2

• Yes, because it makes both equations true.
• No, because it doesn't work with the second equation.
• No, because it doesn't work with the first equation.
• No, because it doesn't work with either equation.
