<em>The options are not given; however, you can take a clue from my explanation to answer your question</em>
Let x be a real number;
Additive identity property implies that; adding x to 0 or 0 to x gives x;
In other words;
Note that x can be replaced with any real number; Take for instance
There are uncountable number of examples;
<em>However, take note that adding 0 to a given digit results in the exact digit and that's the implication of addition identity property</em>
The slopes of two parallel lines must be identical.
We have slope
, so the slope for the parallel line be the same.
Now, to find an equation that also passes through the given point, we use slope-point form,
, where our point 
is substituted for 
.
Now, we convert to slope-intercept form as such.
And we are done. :) We can verify graphically that these are indeed parallel lines. See attached.
