Which graph best represents the equation 12x – 9y = 18?

• 
• 
• 
• 

Which graph best represents the equation -10y – 5x = -15?

• 
• 
• 
• 

Which of the following lines is perpendicular

to the equation -9x = 15 - 3y?

(Hint: put into slope intercept and compare slopes.)

• 6x + 2y - 8 = 0

• x - 3y = -3

• 12x - 24 = 4y

• 6y = 42 - 2x

For each boat he sells, Mick earns $149 in addition to 2% of the purchase price of the boat as commission. If p represents the purchase price of the boat, which equation represents Mick’s commission, c?

• c = 149 + .2p

• c = 149 + .02p

• p = 149 + .2c

• p = 149 + .02c
