Verified answer

3x+14y -17=0

14y = -3x +17........(:14)

y = (-3/14)x + 17/14...........=> a = -3/14

y-yp = a.(x-xp)

y+1= -3(x-3)/14

-3x+9 = 14(y+1)

-3x+9 -14y -14 =0

-3x -14y -5 = 0..........*(-1)

3x +14y +5 = 0

(y+1)=-3/14(x-3)

14(y+1)=-3x+9

14y+14=-3x+9

3x+14y+5=0

3x+14y + Q=0

falta achar o Q

3*3+14*(-1) + Q = 0

9-14 +Q =0

Q= 5

3x+14y+5 =0 <------ respostq

=================================

3x + 14y - 17 = 0

14y = -3x + 17

y = -3x/14 + 17/14

reta //

y = -3x/14 + b

-1 = -3*3/14 + b

b = -1 + 9/14 = -5/14

y = -3x/14 - 5/14

equação

-3x - 14y - 5 = 0

pronto
