Antwoord:
Helling: #color (blauw) (- 6/5) #
Uitleg:
Methode 1: converteren naar standaardformulier: #color (zwart) (Ax + By = C) # met helling #color (zwart) ("" (- A / B)) #
#color (wit) ("XXXXXX") 5y + 6x-2 = 0 #
#color (wit) ("xxxxxx") 6x + 5y = 2 #
#color (wit) ("XXX") #Helling #= -6/5#
Methode 2: omzetten in hellingsbegrenzingsvorm #color (zwart) (y = mx + b) # met helling #color (zwart) (m) #
#color (wit) ("XXX") 5y + 6x-2 = 0 #
#color (wit) ("xxxxxx") 5j = -6x + 2 #
#color (wit) ("XXXXXX") y = -6 / 5x + 2/5 #
#color (wit) ("XXX") #Helling #=-6/5#
