Each of the options are coordinates of the form . So simply plug in the values of each coordinate pair to determine whether or not the above equation is satisfied. For example, looking at A. (2, -5), we have:
So A cannot be the right answer.
Which of the following points lies on the perimeter of the circle given by the equation (x-2)squared+ (y+5)squared = 16?
A. (2,-5)
B. (2,-1)
C. (-2,5)
D. (-2,1)
E. (square root of 2, square root of 5)
How do i even go about finding out the options? -confuzzled-
