Answer:
The equation in standard form is [tex](x + 1)^{2} + (y - 10)^{2} = 4[/tex]
Step-by-step explanation:
The distance from (-1, 12) to (-1, 8) = 4 = diameter of the circle. So, 2 = radius
The center of the circle is at (-1, 10)
The equation in standard form is [tex](x + 1)^{2} + (y - 10)^{2} = 4[/tex]
