Question 1194810
---------------------------------------------------------------
p(0,2) and q(4,0) are two points in a plane ,...  Find the equation of the
(1) circle on pq as diameter.
--------------------------------------------------------------


Center is the midpoint of p and q.
horizontal coordinate, {{{(0+4)/2=4/2=2)));
vertical coordinate, {{{(2+0)/2=1}}};
Size of diameter is {{{sqrt((0-4)^2+(2-0)^2)=sqrt(16+4)=sqrt(20)=2sqrt(5)}}}
radius size is {{{sqrt(5)}}};
radius squared is {{{5}}};
Equation of this circle is {{{highlight((x-2)^2+(x-1)^2=5)}}}
