In the standard \((x, y)\) coordinate plane, line \(m\) is the reflection of line \(l\) across the \(x\)-axis. If the intersection of lines \(l\) and \(m\) is the point \((r,s)\), which of the following must be true? () A. \(r=0\) B. \(s=0\) C. \(...
To solve this problem, recall that the midpoint formula for points (x_1, y_1) and (x_2, y_2) is (((x_1+x_2))2,((y_1+y_2))2 ). Therefore, for points (-1, 3) and (2, 5), the midpoint is (((-1+2))2,((3+5))2 )=(12,82 ), or (12,4 ).反馈...
