Answer:

Parallel.

Step-by-step explanation:

Given the lines:


\begin{gathered} y=2x+5 \\ y=2x-1 \end{gathered}

Comparing with the slope-intercept form of a line: y=mx+b


\begin{gathered} \text{Slope of y=2x+5 is 2} \\ \text{Slope of y=2x-1 is 2} \end{gathered}

Since the slopes of the two lines are the same, they are parallel.
