• y=2/3x+3

What is the equation of the line?

• y = -3/4x + 3
• y = 4/5x + 3
• y = -4/5x + 3
• y = -4/5x

What is the equation of this line?

Write an equation

m = 5/4 through (-4, -3)

• y = 5/4x +2

• y = -5/4x + 2

• y = 2x - 5/4

Write the equation of the line that passes through the point (4, -2) and has a slope of -1/2.

• y = -1/2x + 3
• y = -1/2x
• y = -1/2x + 4
• y = -1/2x - 4

A holiday meal costs $12.50 a person plus a delivery fee of $30.

• y = 30 + 12.5x 
• y = 12.5 + 30
• y = 12.5 + 30x
• y = 30 - 12.5x
