There are 15 animals in a barn.  These animals are horses and chickens.  There are 44 legs in all.  Which system of equations represents the situation?

• x + y = 15
  4x + 2y = 44
• 4x + 2y = 15
  x + y = 44
• x = 2y + 44
  4x = y + 15
• 2x - 4y = 44
  x - y = 15

Write the equation in slope intercept form.

• y = 2x + 3
• y = 3x + 2
• y = 2x - 1
• y = idk

Write the equation that best matches the graph shown.

• y = 4x
• y = 4x - 3
• y = 4/3 x + 4
• y = 4/3 x - 3

^{What is the solution?} 

• 1
• -2
• (1, 2)
• (1, -1)

Solve the system of equations by graphing.

• (4, 7)

• (3, 5)

• (6, 7)

• (5, 3)

Solve the system of equations.

Given: y < 4x + 3

Would shade above or below the line?

• Above

• Below

Given: y < 4x + 3

Would you draw a solid or dashed line?

• Solid

• Dashed

Is (3,-4) a solution to this system?

• yes
• no

Match the system to the graph (solution set is on the left)

• y ≤ 3x   and  y ≤ -2x + 4
• y > 3x   and  y > -2x + 4
• y < 3x   and  y > -2x + 3
• y > 3x   and  y < -2x + 4
