Graphing Solution of System of Equations

Which set of equations is represented by the graph?

• 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

Which set of equations is represented by the graph?

• y = x + 11

  y = x + 2

• y = 2x - 11

  y = - x + 2

• y = 11x - 2

  y = 2x + 1

• y = -2x + 11

  y = x + 2

What is the solution the system of equations?

• (5, 2)

Which set of equations represents the question:

Gavin rides a subway to work. He has two payment options. Option A is to buy a monthly pass for $50, then pay two dollars per ride. Option B is to pay $4.50 per ride. After how many rides will the cost be the same?

• y = 4.5x + 50

  y = 2x

• y = 2x + 50

  y = 4.5x + 10

• y = 4.5x

  y = 2x + 50

• y = 50x + 2

  y = 4.5x

• 90 rides will cost 20 dollars.

• 20 dollars will cost 90 dollars.

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

What is the solution to the system of equations:

y = 4x + 30

• (10, 9)

• (9, 10)

• (10, 10)

• (4, 2)

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?

• 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

What is the solution to the system?

• (0, 3)

• (1, -1)

• (-3, 1)
