To rotate the point \((5, 1)\) 90 degrees counterclockwise around the origin, you can use the rotation formula. The formula for rotating a point \((x, y)\) by 90 degrees counterclockwise is given by:

\[
(x', y') = (-y, x)
\]

So, for the point \((5, 1)\):

1. \(x' = -y = -1\)
2. \(y' = x = 5\)

Therefore, the coordinates after rotation are:

\[
(-1, 5)
\]

Thus, the point \((5, 1)\) rotated 90 degrees counterclockwise around the origin is \((-1, 5)\).
