Answer:
B
Explanation:
Look at the points themselves.
The y value in each case in quad 1 is 1/2 of the x value. So y = 2 is 1/2 of x = 4.
The point in quad 3 is a little different. It looks wrong but it is not. The x value is -2 and the y value is -1. The ratio still holds.
So which equation is correct. It should be B. y = 1/2 x. All the values of y are 1/2 of x
