nadya68 [22]

Answer:

(x+8)² + (y+9)² = 100

Step-by-step explanation:

The equation for a circle on a graph is

(x - a)² + (y - b)² = r²

r represents the radius

a represents the x displacement of the circle's center.

b represents the y displacement of the circle's center.

Point Y (-1,-3) is rotated 180° about the origin. What are the coordinates of its image, point Y prime ?

fgiga [73]

Refer to the figure shown below.

When the point Y (-1,-3) is rotated 180 about O, it sweeps a semicircular arc to the point Y' (1,3).
The radius of the semicircle is
$r = \sqrt{1^{2} + 3^{2}} = \sqrt{10} \\ or \\ r = \sqrt{(-1)^{2} + (-3)^{2} } = \sqrt{10}$

Answer: 3. Y' (1,3)
