physics help...I HAVE A TEST TOMORROW !!?

ok there were some equations that my physics teacher had on the board..he said it was too advanced for my class, but we wud be tested on it anyway. so it's not in the book

i lost the sheet of paper that had the equations on it.

the equations were about projectiles and motion and vectors. and it was like
"delta" y = Viy+1/2atsquared
and it was like delta y is = to 0.

so wat is the correct form of this equation...and is it the same for "x" cas he had that equation on the board too.
THANX SO MUCH

o ya...ther was also somehting bout final velocity in the "y" or something like
"delta" y (subscript) f=something

so plz do the best u can tysm
