Answer:
Center: (9, 4)
Radius: 20
Explanation:
(x - 9)² + (y - 4)² = 400
The Circle Formula:
(x - h)² + (y - k)² = r²
where (h, k) is center points, r is radius
Rewrite the equation:
(x - 9)² + (y - 4)² = 20²
Identify following:
h = 9, k = 4, radius = 20
Answer:
It's B
Step-by-step explanation:
Slope intercept form is Y=mx +b
(b is sometimes there when slope intersects the y axis)
To determine the slope, you can use the following formula:
(y2-y1)/(x2-x1)
