We are finding slope:
change in y / change in x
277 - 205 / 2007 - 1997
72 / 10
7.2
<h2 /><h2>
~ 7</h2><h2>
</h2>
9*(x-1)=2x-7
First get rid of your parenthesis by distributing.
9x-9=2x-7
Then all you have to do is isolate the variable
9x=2x+2
7x=2
so x= 2/7
i think its 3√3 because that seems like the logical answer to me.
The answer is AA Similarity
