Some equations have the form y=kx, where k is a number.
kumpel [21]

Answer:

y=x+3

Step-by-step explanation:

The equation "y=x+3" cannot be written in the form y=kx because <u><em>the form </em></u><u><em>doesn't use addition</em></u><u><em> as a basic operation.</em></u> Let's try verifying the choices:

y=x is possible<em> </em>if the value of k is 1, provided that both y and x are of the same value.

y/2=x is possible because y=2x, provided that 2 is the value of k.

y=-1/10x is possible because -1/10 is the value of k. This is just the same with y=kx.
