Show that the triangle with \((-3,2),(1,1)\), and \((-4,-2)\) as vertices is an isosceles triangle.
Find the point \(\mathrm{Q}\) that is \(3 / 4\) of the way from the point \(\mathrm{P}(-4,-1)\) to the point \(\mathrm{R}(12,11)\) along the segment PR.
Given the three points \(\mathrm{P}(4,3), \mathrm{Q}(4,7)\), and \(\mathrm{R}(7,3)\). Find the lengths of \(\underline{P Q}\) and $\underline{P R}$.
A line segment \(\mathrm{AB}\) is \(7(1 / 2)\) in. long. Locate the point \(\mathrm{C}\) Between \(\mathrm{A}\) and \(\mathrm{B}\) so that \(\mathrm{AC}\) is $3 / 2$ in. shorter than twice CB.
Suppose \(\mathrm{f}=\\{(\mathrm{x}, 2 \mathrm{x}-3)\\}\). Choose any three points of the graph of \(\mathrm{f}\) and show that they lie in a line.
