Standard form of equation of a circle calculator
A linear equation is a mathematical equation that describes the location of the points on a line in terms of their coordinates. What are the forms of line equation? Common forms of a line equation are the slope-intercept form (y = mx + b), the point-slope form (y - y1 = m(x - x1)), and the two-point form (y2 - y1 = m(x2 - x1)).We can use a technique called completing the square to rewrite such an equation so that we can quickly identify the circle's center point (h,k) and the radius. OUR GOAL: To find the standard form of the given circle equation by factoring. In order to factor the original equation, we will need to add a "magic number" to BOTH sides of the equation.The standard equation of a circle is represented as: (x – a)^2 + (y – b)^2 = r^ 2. Where, r = radius of the circle. (a,b) = centre of the circle. This equation is also termed as circle-radius form. (x, y) are the point at the boundary or circumference of the circle.
