Question

What is the equation of the circle in standard form see attachment

Answer 1

Center (-1,1), radius 5 so

$(x - -1)^2 + (y - 1)^2 = 5^2$

$(x+1)^2 + (y-1)^2 = 25$

Third choice

Answer 2

Answer:

○ (x + 1)² + (y - 1)² = 25

Step-by-step explanation:

According to one of the Circle Equations, (X - H)² + (Y - K)² = R², all the negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY careful inserting the center into the formula with their CORRECT signs. Then in the end, square the radius.

The radius is five, so squaring this will give you twenty-five.
