True this is because of the number of angles a quadrilateral has which is 4

factorising the first denominator
x²-2x-3 = x² -3x+x-3 = (x+1)(x-3)
(a) 
finding LCD
(b) LCD of (x-3)(x+1) and (x-3) is (x-3)(x+1)
(c)

(d)

The slope is three
Step-by-step explanation:
count up from the bottom point until you reach -1 then go over one and you will get 3/1.
They are closer in values.
