Answer:

it is 250 percent increase

Step-by-step explanation:

it is cuz if you multiply 20 times 2 you get 40 but you need 50 so you say ok well half of 20 is ten so add a 50 percent in there if it makes sense

I'm really sorry, I'm not the best at this, but I did all the equations the best to my knowledge and came up with these 3 answers
(2,-1) which equaled -7
(5,4) which equaled -11
and (0,-9) which equaled - 9
Again I'm really sorry if this didn't work. :( God bless and good luck with future lessons.
