What is the equation of the line?

a.) y=4/3x
b.) y=-4/3x
c.) y=3/4x
d.) y=-3/4x

The answer is B) y = -4/3x. This is because if you measure across from where the line hits the corner of a square, and then up back to the line, you get 4 vertically and 3 horizontally. It's negative because of the direction that the line is going. I hope this helps!
