Best ResponseYou've already chosen the best response.0the form for the equation of a vertical line is x=c (c is a constant) horizontal is is y=c

Best ResponseYou've already chosen the best response.0so the vertical line is x=4

anonymous

Best ResponseYou've already chosen the best response.0i dont understand how to get it

Best ResponseYou've already chosen the best response.0the radius is the distance from the origin to an endpoint on the circle

anonymous

Best ResponseYou've already chosen the best response.0subtract the y coordinate of the origin from the y coordinate of the endpoint connected by the vertical line

anonymous

Best ResponseYou've already chosen the best response.0that would be subtracting the x coordinate from the y coordinate.

Best ResponseYou've already chosen the best response.0try drawing the circle on graph paper with origin (4,4) and it should become clear
