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.

Write a linear equation given the x-intercept is 5 and the y-intercept is -4.

Solve for x
32 - x = -3(x - 4)

• x = -10

• x = -16

• x = -18

• x = -22
