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.

$y=\frac{9}{2}(x-2)+12$
