# What is the general form equation of a circle?

Standard form for the equation of a circle is **(x−h)2+(y−k)2=r2**. The center is (h,k) and the radius measures r units. To graph a circle mark points r units up, down, left, and right from the center.

## What is the general equation of a circle?

We know that the general equation for a circle is ( x – h )^2 + ( y – k )^2 = r^2, where ( h, k ) is the center and r is the radius. So add 21 to both sides to get the constant term to the righthand side of the equation.

## How do you write standard form of a circle in general form?

The standard form of the equation of a circle is (x−A)² + (y−B)² = C. We can write the general form of the circle equation to the standard form by calculating the unknowns A, B, and C from the general equation’s parameters D, E, and F. Luckily, that math is easy! C = A² + B² − F.

## How do you find the general form?

The general form of any equation contains the degree of variables in decreasing order. The general form of a linear equation is ax + b = 0. The general form of a linear equation in two variables is ax + by + c = 0. We know that the general form of the equation of lines can be found using the slope and y-intercept.

## How do you convert to general form?

Thus, to convert to general linear form, first isolate x and y on one side and the constant term on the other side. Next, if any of the coefficients are fractions, multiply the entire equation by the least common denominator of all the fractions. Example: Convert y + 1 = (x – 2) to general linear form.
