The equation of a circle:
(h,k) - the coordinates of the center
r - the radius
Plug the coordinates of the points into the equation and check:
The answer is F(-2,6).
(h,k) - the coordinates of the center
r - the radius
Plug the coordinates of the points into the equation and check:
The answer is F(-2,6).
to make a perpendicular function from another we must take its slope and make two transformations
the slope of y=1/3x is 1/3
the transformations:
1.
reverse the number
2.
and change the sign
ok we have the slope now need the general equation of the line
where m is the slope , b a cut point and (x,y) a point
so, we have the slope=-3 , and the point (2,-3) we can replace to find b
now we can replace b and the slope to have the final equation
