2 (x-1)squared+2 (y+2)squared=7 I got center=1,-2 and r=1.9. Does that look correct?

Your radius appears to be rounded to one decimal place...it is actually: $\displaystyle r=\sqrt{\frac{7}{2}}$

When graphing the circle do i graph it 1.9 away from center or 1.3?
The circle will be the set of all points that are a distance $\displaystyle r$ from the center. So, approximately 1.9 units from the center.
