A perpendicular bisector passes through the segment's midpoint and has a slope that is the negative reciprocal of the segment's slope.
Desmos Shortcut: Plot \( A(-2, -3) \) and \( B(4, 9) \). Use midpoint formula to plot \( M(1, 3) \). Enter \( y - 3 = m(x - 1) \) and adjust \( m \) until the line is perpendicular to segment \( AB \).
Step 1: Find the midpoint \( M \) of segment \( AB \): \[ M = \left(\frac{-2 + 4}{2}, \frac{-3 + 9}{2}\right) = (1, 3) \] Step 2: Find the slope of segment \( AB \): \[ m_{AB} = \frac{9 - -3}{4 - -2} = 2.00 \] Step 3: The perpendicular bise...
