of y = -2x and Y = 2x + 1

In general, to find horizontal asymptotes you find the limit as x approaches infinty and the limit as x approaches negative infinity. If either of these approaches a value other than infinity, you have a horizantal asymptote.
As the others have said, your particular equations don't have horizontal asymptotes because both of the limits at infinitiy approach positive or negative infinity.

Those are straight lines. There are no horizontal asymptotes.
If you meant y = -2/x, then y = 0 is a horizontal asymptote.

since these problems are linear, they have no horizontal asymptote.
most of the time if it is possible, all you do is find the inverse of the problem and then solve for y.
just switch the x and y values and solve for y. Whatever y cannot be, is your horizontal asymptote.

you'd take the limit as x goes to infinity.
2* infinity is infinity
2*infinity +1 is infinity.
No asymptote

no horizontal asymptotes for both!
