Answer:
a) 20%
b) 50%
c) -75%
Step-by-step explanation:
Mathematically, percentage change is;
(new value -old value)/old value * 100%
(i) (90-75)/75 * 100%
= 15/75 * 100% = 20%
ii) (60-40)/40 * 100%
= 20/40 * 100% = 50%
iii) (5-20)/20 * 100% = -15/20 * 100% = -75%
Answer: If the first one is addition, which I'm pretty sure it is, the answer is
1 1/10

Step-by-step explanation:
The easiest way to find the slope is to find 2 points that are at an exact point. (-3,1) and (2,-3) are exact points. Start at (-3,1) and count to the right 5 and go down four. The slope would be 
or 
.
I hope my explanation makes sense! :) If it doesn't make sense I can try to explain it better!
