You have to make an equation that i forgot what was called but you just take
x+y=10 and multiply it by -2 so the y’s can cancel out
so you’ll end up with:
-2x-2y= -20
(+) x+2y=14
you’ll get : x = -6
then you plug in -6 for x, solve for y and your coordinates will be
(-6 , 10)
Answer:
y= -1/4x
Step-by-step explanation:
If you use the pothaorian theorym (A squared + B squared= C squared) youll be able to figure out the right answer is 65.
