What is the equation of this line in the form
y = mx where m is the slope?

• y = 60x + 100
• y = 60x
• y = 20x + 2
• y = 60x - 100

Does this graph represent a proportional relationship?  

• No, because it doesn't pass through the origin.
• Yes, because it doesn't pass through the origin.
• Yes, because it intersects the y axis.
• No, because it intersects the x axis.

A system of two linear equations has infinitely many solutions. One equation is 2x - 3y = 8 . Which equation below could be the other equation?
