X - y = 0

A, B, C, or D

D

Step-by-step explanation:

Using the equation y = mx + b.

m represents the slope

b represents where the line crosses the y axis.

We can attempt to set up the equation given in the same way.

x - y = 0

Add y to both sides and the 0 can drop out.

x = y

This is also equal to:

y = x

In this equation the m is equal to 1 and the b is equal to 0.

Taking this into account the answer is D.
