Laura has a mass of 60 kg and is sitting 265 cm from the fulcrum of a seesaw. Bill has a mass of 50 kg. How far from the fulcrum must he be to balance the seesaw? (Hint: The distance from the fulcrum varies inversely as the mass.)

The cost of a pencil varies directly with the number sold. If 5 pencils cost $0.45, write the direct variation equation (not formula) and find the cost of 7 pencils (Choose one answer for equation and one for cost)

• Cost: $1.59

• Cost: $0.32

You must choose all correct answers. Find the x-intercepts and y-intercepts for the equation 6x - 3y = -18.

• y-intercept = 6

• x-intercept = 8

• x-intercept = -3

• y-intercept = -6

• x-intercept = 0

Find the slope of 2x - 3y = 7.
