Yes, they are parallel to each other. See full explanation of why below.

#### Explanation:

Two lines are parallel if they have the same slope.

You can find the slope of a line using the slope-intercept form of the equation which these two equations are already in.

The slope-intercept form of a linear equation is:

Where

Both of these equations have the same slope of

Therefore these two lines are parallel.
