use pythagorean theorem
find legn height and leg width
from -1 to 6, the distance is 7
from -2 to 2, the distance is 4 so
4^2+7^2=c^2
solve for c
16+49=c^2
65=c^2
square root both sides
√65=c
the answer is √65
(the basic equation is \(c= \sqrt{(y1-y2)^2+(x1-x2)^2}\) x1-x2 means the first x minus the second x)
