(c) ii and iii: a + 2b - 1 = a+b-1+b
(d) i and iii: x+(y-z) = x-(z-y)
(e) ii and iii: (a-1)² = (1-a)²
(f) i and ii: 3a-b-1-1 = 3a+b-2-2b

Work shown above! Answer is C
Answer:
-1
Step-by-step explanation:
x y x2 y2
-3,5 and 5,-3
-3-5/5-(-3)
-8/8
the slope is -1/1
y2-y1 / x2-x1=slope of the two points
