Answer: A,  C   and  E

Step-by-step explanation:

All proportional equations or lines always go through the origin because when it's x coordinate is 0, it's y coordinate has to be 0 too.

It is also a straight line  .

And k will always be the constant value, as if    y = kx.  K is the constant change or the slope.
