Describe the end behavior of the graph.

What is the End behavior on the left side

• x →-∞, y→∞
• x →∞, y→-∞
• x →-∞, y→-∞
• x →∞, y→∞

What is the solution to the system of equations that is represented in the graph?

• (3, 2)

• (-2, 3)

• (3, -2)

• Infinite

Which system of equations could represent the following word problem?

The sum of two numbers is 30. The first number is twice the second minus 5.

• a + b = 30

  2a = b - 5

• a - b = 30

  2a = b - 5

• a + b = 5

  a = 2b -30

• a + b = 30

  a = 2b - 5
