Can anyone with this and so much!

This is for reflection across the y-axis

A (-2,2)

B (-5,-1)

C (-1,-2)

A" (-6, 3)

B" (-9, 0)

C" (-5, -1)

Step-by-Step explination:

You just add 4 to x then make it negative since it is reflecting over the y-axis(the vertical line). Then add 1 to y but it stays the same after that.

Sorry kind of bad at explaining but thats the best i can do for this problem, hoped it helped...

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
