Answer:
A) The coefficients of x in the two equations are the same because they have the same slope.
Explanation:
For two lines to be parallel, them must have the same slope. In the slope-intercept form of a linear function:

the coefficient of
(
) is the slope.
In the two given equations:
we can identify both x-coefficients as 2. Therefore, the lines have the same slope, and thus, they are parallel.
We can identify the answer choice that details this as A.
Further Note
A coefficient is the number multiplied by a variable.
