Answers are provided in three formats:

We can move the x term to the left side by adding 2x to both sides. We have seen that we can transform slope-intercept form equations into standard form equations.

But why should we want to do this?

There are a number of reasons. First, standard form allows us to write the equations for vertical lines, which is not possible in slope-intercept form.

Remember that vertical lines have an undefined slope which is why we can not write them in slope-intercept form. This example demonstrates why we ask for the leading coefficient of x to be "non-negative" instead of asking for it to be "positive".

For horizontal lines, that coefficient of x must be zero. This topic will not be covered until later in the course so we do not need standard form at this point. However it will become quite useful later.

A third reason to use standard form is that it simplifies finding parallel and perpendicular lines. Let us look at the typical parallel line problem. The usual approach to this problem is to find the slope of the given line and then to use that slope along with the given point in the point-slope form for a linear equation.

Any line parallel to the given line must have that same slope. Of course, the only values affecting the slope are A and B from the original standard form.Online Calculator Math Calculator Geometry Calculator Circle Calculator Equation of a Circle Calculator.

Top. From the circle equation one can identify the center and radius of the circle. We can write the equation in two different manner.

One is the general form and other one is the standard form. The equation of a circle in standard. Online calculator to determine the general form linear equation for a line from two coordinates. Evaluate the circle equation %28x - 2%29%5E2%2B%28y%2B5%29%5E2%3D81 = 0 To see the diameter, circumference, and area of this circle, visit our calculatorFounder: Don Sevcik.

Find the equation of the circle passing through the points P(2,1), Q(0,5), R(-1,2) Method 2: Use Centre and Radius Form of the circle.

Standard Form of a Decimal Number |
The standard form general equation for any conic section is: Circles are defined as a set of points that are equidistant the same distance from a certain point; this distance is called the radius of a circle. |

Example 1: Rewriting Equations in Standard Form |
The Chinese system is also a base system, but has important differences in the way the numbers are represented. |

Let the center and radius of the circle be C(a,b) and r. Finding the Parametric Equations for a Line Given Two Points Example: Find the parametric equations for the line through the points (3,2) and (4,6) so that when t = 0 we are at the point (3,2) and when t = 1 we are at the point (4,6).
