Answer:

  4x +3y = 10

Step-by-step explanation:

The radius CD has slope Δy/Δx = (1-(-2))/(8-4) = 3/4.

The equation for the perpendicular line through point C(4, -2) can be written as ...

  Δx(x -4) +Δy(y -(-2)) = 0

  4(x -4) +3(y +2) = 0

  4x +3y -10 = 0 . . . . . . general form equation for the line

  4x +3y = 10 . . . . . . . . .standard form equation for the line
