The Frederick County Fair costs $15.00 to get in and $2.50 per ride, while the Montgomery County Fair costs $10.00 to get in and $3.00 per ride. Which equations could be used to determine how many rides you would need to go on for both fairs to be of equal value? 

• 15x + 2.5 = 10x + 3
• 15 - 2.5x = 10 - 3x
• 15 + 2.5x = 10 + 3x
• 15 - 10 = 2.5x + 3x

At Gamestop you can buy a Xbox One for $150.00 and each game to go with it would cost $24.00. Or, you can buy a Playstation 4 for $180.00 and each game for $20.00. Write an equation to determine how many games would need to be purchased for the cost to be equal? 

• 150x + 24 = 180 + 20x
• 150 + 24x = 180 + 20x
• 180 - 150 = 24 x + 20x
• 150 - 24x = 180 - 20x

10x + 9 = 4x - 9

• 3
• -3
• -18

7x = 3x + 24

What is the slope-intercept equation?

• y = 6x + 3

• y = 6x + 2

• y = 3x + 2

• y = 3x - 2

What is the slope-intercept form?

• y = 5/3x

• y = 3/5x + 21

• y = 2/3x

• y = 2/3x + 21

What is the equation of this line?

• y = 2x +2

• y = 2x -2

• y = -1x + 2

• Can't tell

Write the equation of the line in slope intercept form.

• y = 3x + 6

• y = 6x + 3

• y = -3x - 6

• y = 3x - 6

Is this graph a function or not a function? 

• Function, because it passes the vertical line test
• Not a Function, because it does not pass the vertical line test
• Not a function, because of a positive slope
• Function, because it is linear

Which graph shows a non proportional relationship between x and y?
