To rotate a point \((x, y)\) about the origin by 270 degrees counterclockwise, you can use the following transformation rule:

\[ (x, y) \rightarrow (y, -x) \]

Now, apply this rule to the point \(M(0, 4)\):

  1. Identify the coordinates of M: \(x = 0\) and \(y = 4\).

  2. Apply the rotation formula: \[ M' = (y, -x) = (4, -0) = (4, 0) \]

Thus, the image of point \(M\) after a 270-degree counterclockwise rotation about the origin is:

\[ M' = (4, 0) \]
