Well... the two rectangles are in the picture below, those are their coordinates
so, you can pretty much see how long one side is, since you can simply count the units on the grid
running a tests on them.... hmmm they'd be similar is the length of the corresponding sides on each figure, give the same ratio
I hope you can read this. If you have any questions or need a better photo, feel free to ask.
Answer:
first : x²-10x=39
{-3;13}
second : multiply both sides by 1\4
last is : {-1;5}

the x is very important since it is the input value while y is the output
so y depends on the x
