from -4 to 4 is right 8 from -2 to 6 is up 8
|dw:1425610068411:dw|
use pythagoras to find the distance
\[8^{2}+ 8^{2}= c ^{2} \]
\[64^{2}+64^{2}=c ^{2}\]

\[4096+ 4096=c ^{2}\]
\[8192=c ^{2}\]
\[\sqrt{8192}= c ^{2}\]
\[90.5=c ^{}\]
That's all my work, and I dont know how to get any of the answer choices

@iambatman
\[64+64=128\] so \[\sqrt{128}\]
why do you add it?
oh, I see!
Thank you! :)
