The equation of a circle in standard form is

where (h, k) is the center of the circle, and r is the radius if the circle.
We need to find the radius and center of the circle.
We are given a diameter, so to find the center, we need the midpoint of the diameter.
M = ((-6 + 6)/2, (6 + (-2))/2) = (0, 2)
The center is (0, 2).
To find the radius, we find the length of the given diameter and divided by 2.





Answer:
D)
Step-by-step explanation:
Answer:y = -4
Step-by-step explanation: In order to find the slope by these two points, (6,-4), and (-4,-4), you must use the slope formula:
rise/run, which is this case, is y2-y1 / x2 - x1 <--- this is the slope formula
Let 6 be x2, -4 be x1, y2 be -4, and y1 being -4, plug these numbers in.
-4-(-4) / 6- (-4)
-4 + 4/ 6 +4
0/10 The slope of the line is zero, with a y-axis at -4. We know this because there is a zero in the final result and the y- coordinate between (6,-4) and (-4,-4) do not change in the slightest.
The final answer is then y = -4
5x =61-6
5x= 55
X = 55/5
X = 11
Answer:
X and y are supplementary.
