Answer:
C
Step-by-step explanation:
(2,-5) move up three steps is (2, -2). if you draw it on a paper(and draw lines to connect them), you can see that they form a right triangle. apply a²+b²=c² and you should get 3²+2²=(√13)²
Y=1
x=50 y=5 50 is 10 times more than 5, the proportion is x is 10 times more, so you always divided 10 from x
