how far should point j be from the x - axis? units

Explanation:

Step1: Determine the y - coordinate of point J

The distance of a point \((x,y)\) from the \(x\) - axis is given by the absolute value of its \(y\) - coordinate. For point \(J\), assume the coordinates of \(J\) are \((-1,4)\) (by observing the grid).

Step2: Calculate the distance from the \(x\) - axis

The distance \(d\) of a point \((x,y)\) from the \(x\) - axis is \(d=\vert y\vert\). Since \(y = 4\) for point \(J\), and after a transformation (assuming it's a rigid transformation like translation, rotation, or reflection which preserves distances), the \(y\) - coordinate of \(J'\) will have the same absolute value as the \(y\) - coordinate of \(J\).

Answer:

\(4\)
