Graph a triangle (lmn) and rotate it 180° around the origin to create triangle l′m′n′.
describe the transformation using words. make sure you refer to the characteristics and the coordinates.
draw a line through points l and l′ and through m and m′. what do you notice about the lines you drew? do you think you would notice the same characteristics if you drew another line through points n and n′? how do you know?

answer is c

step-by-step explanation:

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4

im super bad at school but u for some reason need to have points to ask questions and you get points by answering so thats all im doing sorry for t r o l l i n g
