What is the equation of this circle in standard form? (x+1)2+(y+2)2=49 (x−1)2+(y−2)2=7 (x−1)2+(y−2)2=49 (x+1)2+(y+2)2=7 A circle on a coordinate plane centered at begin ordered pair negative 1 comma negative 2 end ordered pair. The horizontal x-axis ranges from negative 10 to 10 increments of 1. The vertical y-axis ranges from negative 10 to 10 in increments of 1. The circle passes through begin ordered pair negative 6 comma negative 2 end ordered pair, begin ordered pair negative 1 comma 5 end ordered pair, begin ordered pair 6 comma negative 2 end ordered pair, and begin ordered pair negative 1 comma negative 9 end ordered pair.

(x+1)² + (y-1)²=64

(x+1)² + (y-1)²=8²

(x-h)² + (y-k)² = r²

center of the circle (-1,1), r=8.
