  see below

Step-by-step explanation:

The point (4, -2) tells you the constant of proportionality of this line through the origin is ...

 k = -2/4 = -1/2

Then the equation of the line is ...

  y = kx

  y = -1/2x

C. y= -2x because -2 multiplied by -2 is positive four. The reason why it is negative is that when two negatives are multiplied together, they undo each other, thus becoming a positive sign.
