Question

reflect point b across the x-axis.
what is the distance from each point to the x-axis?
point distance
b?
b1 unit 2 units 3 units 4 units

Explanation:

Step1: Determine the distance formula from a point to the x - axis

The distance from a point \((x,y)\) to the \(x\) - axis is given by \(|y|\).

Step2: Analyze the coordinates of point \(B\) and \(B'\)

Looking at the graph, for point \(B\) and its reflection \(B'\) across the \(x\) - axis. The \(y\) - coordinate of \(B\) is \(- 2\) and the \(y\) - coordinate of \(B'\) is \(2\). Using the formula \(|y|\), for point \(B\), \(|y|=|-2| = 2\) and for point \(B'\), \(|y| = |2|=2\).

Answer:

For point \(B\), the distance is \(2\) units. For point \(B'\), the distance is \(2\) units.
