# How do you graph a circle?

## How do you graph a circle?

Graphing a circle anywhere on the coordinate plane is pretty easy when its equation appears in center-radius form. All you do is plot the center of the circle at (h, k), and then count out from the center r units in the four directions (up, down, left, right). Then, connect those four points with a nice, round circle.

## How do you make a circle function?

The equation of a circle appears as (x – h)2 + (y – v)2 = r2. This is called the center-radius form (or standard form) because it gives you both pieces of information at the same time. The h and v represent the coordinates of the center of the circle being at the point (h, v), and r represents the radius.

How do I graph an equation?

To graph an equation using the slope and y-intercept, 1) Write the equation in the form y = mx + b to find the slope m and the y-intercept (0, b). 2) Next, plot the y-intercept. 3) From the y-intercept, move up or down and left or right, depending on whether the slope is positive or negative.

How to plot points on Desmos?

Like this: One or two conditions via {range function} at the end.

• Locate the y-intercept on the graph and plot the point.
• Tap the gray points of interest to see their coordinates.
• In Desmos,you can plot points one at a time,a few on a line,or all in a table,whichever you prefer.
• ### How to graph points on Desmos?

When creating a table in Desmos, points can be connected by clicking and long-holding the icon next to the dependent column header. Choose from two different styles. This is also a great way to graph shapes in the calculator. Using the Polygon Function to Connect Points

### How to use Desmos calculator?

Use Desmos Tools for Math Details: Access Desmos Tools Within an Activity Select Tools, and then click Desmos Graphing Calculator, Desmos Scientific Calculator, or Desmos Geometry. A separate Realize Desmos window opens for the tool you selected. Use the Graphing Calculator.

How do I graph a circle?

follow these steps: Realize that the circle is centered at the origin (no h and v) and place this point there. Calculate the radius by solving for r. Plot the radius points on the coordinate plane. Connect the dots to graph the circle using a smooth, round curve.
