WebA linear equation is represented as a line graph. In order to draw the line graph we require several pairs of coordinates. These coordinates represent the relationship given in the... WebEquation of a circle. The general equation of a circle normally appears in the form \({x^2} + {y^2} + 2gx + 2fy + c = 0\). where \(( - g, - f)\) is the centre of the circle . and \(\sqrt {{g^2} + {f^2} - c}\) is the radius.. Notice that for the circle to exist, \({g^2} + {f^2} - c\textgreater0\). Look at the following worked examples.
