Pretty sure ( -2,-7) because from -1 you go over one then each y is going down 3 so -4 - 3 is -7
Answer:
x = (+ - ) 9
Step-by-step explanation:
x^2 = 81
u know how u can sometimes cancel something out by doing the opposite.
This is one of those times as well. the opposite of ^2 = square root.
so if we take the square root of both sides, this will cancel out the^2 on the left side.
sqrt (x^2) = sqrt(81)
x = (+-) 9.....thats a positive and a negative sign...because the sqrt of 81 is both 9 and -9.
I’m sorry if I’m wrong but I do think your answer is X=22y^-1
