System of Linear Equations Graphing

Which set of equations represents the question: Tim and Jack both had donut trucks. Tim had 5 donuts ready to fry from the night before, and made 1 donut every 2 minutes. Jack always gives away the first 30 donuts he makes to a local shelter. He can make 4 donuts a minute. How long before they have the same number of donuts to sell?

• y = 2x - 5

  y = 4x + 30

• y = 1/2x + 5

  y = 4x - 30

• y = -1/2x + 5

  y = - 4x - 30

• y = 5x + 1/2

  y = -30x + 4

• It's not this.

• It will take 10 minutes to make 10 donuts.

Which set of equations represents the question:

Brayden was on the 11th floor of his apartment building. He descended the stairs at a rate of two floors per minute. Mayce started on the 2nd floor of the apartment building and went up one flight of stairs per minute. On what floor will they meet?

• y = x + 11

  y = x + 2

• y = 2x - 11

  y = - x + 2

• y = 11x - 2

  y = 2x + 1

• y = -2x + 11

  y = x + 2

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.
