The equation of circle with center (g,f) and radius r is given by,
(x-g)² + (y-f)² = r²
Now, compare equation (x-2)² + (y+4)² = 6 with the above equation.
g = 2 and f = -4
Therefore, center of the circle is (2,-4)
Answer:
The values of
and
so that the two linear equations have infinite solutions are
and
, respectively.
Step-by-step explanation:
Two linear equations with two variables have infinite solution if and only if they are<em> linearly dependent</em>. That is, one linear equation is a multiple of the other one. Let be the following system of linear equations:
(1)
(2)
The following condition must be observed:
(3)
After some quick operations, we find the following information:
,
, 
The values of
and
so that the two linear equations have infinite solutions are
and
, respectively.
