The graph of which of the following equations is a line parallel ot the graph of x-5y=8

Since you don't show the graph, all I can do is to tell you how to identify which function is parallel to the x-5y=8.

First let's rearrange the function.

x-5y=8

5y=x-8

y=1/5x-8/5.

Thus, it gives us the slope of the function, which is 1/5.

And the function that is parallel to the graph would have the SAME slope. Which is 1/5. So all you need to do is to find which function has the SAME SLOPE, in this case: 1/5.
