It can be variety of problems but a x and y plot would be ideal demonstration as you need to make a hypothesis of what you think the pattern for it is then use it for each x and y problem through put the plot
0.63x12= 7.5 so the answer is 7.5
Pythagorean
Theorem as follows: A^2+B^2=C^2
y = 4x - 3 would be it !!!!
5+3 = 8
8 is 100%
3/8 = 37.5%
I feel like I might be wrong haha sorry if I am
