Answer:
(x + 2)^2 + (y - 3)^2 = 9
Step-by-step explanation:
The standard formula for the equation of a circle would be:
(x - h)^2 + (y - k)^2 = r^2
where (h, k) is the center and r is the radius.
From the picture, the center is given to be (-2, 3) and by counting the squares, we can say the radius is 3. We can plugs these values into the equation.
(x + 2)^2 + (y - 3)^2 = 9
The answer is 5/2
y2-y1/x2-x1
9-4/7-5 = 5/2
