Answer:

A

Explanation:

Remember that parallel lines have the same slope.

The y-intercept does not matter.

We have the two equations:


y=x+4

And:


y=x-2

The slope is the coefficient in front of the x.

In the first equation, we can rewrite it as:


y=(1)x+4

Therefore, the slope of the first equation is 1.

Similarly, for the second equation, we can rewrite it as:


y=(1)x-2

The slope of the second equation is also 1.

Therefore, since their slopes are equivalent, they are parallel.

Thus, our correct answer is A.
