Step1: Properties of dilation
Dilation is a transformation that changes the size of a figure but not its shape. When a line segment is dilated with a center of dilation on the line segment itself, the slope of the original line segment and the dilated line segment remains the same.
Step2: Determine the slope
Since \(\overline{AB}\) is dilated to form \(\overline{A'B'}\) with a center of dilation \(O\) on \(\overline{AB}\), and the slope of \(\overline{AB}\) is \(3\), the slope of \(\overline{A'B'}\) is also \(3\).
Step3: Position of \(\overline{A'B'}\)
Because the center of dilation \(O\) lies on \(\overline{AB}\) and we are performing a dilation, \(\overline{A'B'}\) passes through point \(O\).
