Using ΔPQR, find the equations for the following lines. Homework Help ✎
The perpendicular bisector of
.The median line that goes from Q to the midpoint of
.The altitude of ΔPQR from Q to side
.
1. Find the slope of the ⊥ line.
2. Find the midpoint (D)
3. Substitute into the point-slope form.
1. Given the points D and Q, find the slope
2. Use the point-slope form of a line to find an equation.
1. Find the slope of the ⊥ line.
2. Then using the slope and pt. Q, use the form y = mx + b to find b.
3. Then substitute back m and b back into the form.
