The answers are not different but the breakdown is.

Front Doors=6 3/4" X2 Rear Doors=6 3/4"* X2 Rear Deck=6x9" X2 Front Near Window=3 1/2" X2 center of Dash= 3 1/2" X1 *If Available
X2 + 44x + 43
we have the points (3,4) and (8,-6) let x1=3 y1=4 x2=8 y2=-6 slope=(y2-y1)/(x2-x1) =(-6-4)/(8-3) =-10/5 =-2
we have the points (3,4) and (8,-6) let x1=3 y1=4 x2=8 y2=-6 slope=(y2-y1)/(x2-x1) =(-6-4)/(8-3) =-10/5 =-2
if: y = x2 y = x + 6 then x2 = x + 6 => x2 - x - 6 =0 => (x - 3)(x + 2) = 0 => x = 3 or -2 => y = 9 or 4 respectively, ie the points (3, 9) and (-2, 4).
m=(y2-y1)/(x2-x1)=[3-(-3)]/[(-4)-2]=6/(-6) m=-1

-x2 = x - 6 x2 + x - 6 = 0 (x - 2)(x + 3) = 0 x ∈ {-3, 2}
