(6,7) and (4,2)

• 2/5
• -5/2
• 5/2
• -1/2

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?

• 4x + 6y = 3
  13.5x - 13y = 6
• x + y = 4
  x - y = 6
• 4x + 6y = 13
  3x + 7y = 13.5
• 4x - 6y = 13
  3x - 7y = 13.5

Write a linear equation in the form of y=mx+b

• y = -4x +6

• y = 6x - 4

• y = 4x - 6

• y = 3x - 2

What are the equation and slope of the line shown on the grid?

• x = 6; slope is zero

• y = 6; slope is zero

• x = 6; slope undefined

• y = 6; slope undefined

Which table shows y as a function of x?

• 
• 
• 
• 

Write the equation for the line in slope-intercept form.

• y= -1x+3

• y= 4x+3

• y=1/4x+3

• y= -4x+3

What is the solution to this system of equations?
3x + 2y = 16
7x + y = 19

Hint: Which ordered pair makes BOTH equations TRUE?

• (-2,5)
• (-2,-5)
• (2,-5)
• (2,5)

Write a linear equation in the form of y=mx+b

• y = 2x + 10

• y = 3x - 2

• y = -x + 1

• y = 7x + 2
