How do you write the equation of the locus of all points in the coordinate plane 10 units from (–6, 9)?
circle with equation
The points will lie on the circumference of a circle with centre (-6 ,9) and radius of 10.
The standard form of the equation of a circle is.
where (a ,b) are the coordinates of the centre and r, the radius.
here a = -6 , b = 9 and r = 10
#rArr(x+6)^2+(y-9)^2=100" is the equation of the locus"#
