Answer:
E. y = -4x
Explanation:
The line goes through the origin, so the equation is of the form ...
y = kx
The constant of proportionality k has the value ...
k = y/x
The given point is (x, y) = (2, -8). Using these values in the expression for k, we have ...
k = -8/2 = -4
Then the equation is ...
y = -4x . . . . matches E
