#### How do you find the coordinates of a point?

To find the coordinates of a point on a graph using Desmos, you can follow these steps:

- Open the Desmos Graphing Calculator in your web browser or mobile app.
- Create the graph or enter the equation(s) that represent(s) the graph you are working with.
- Locate the point on the graph for which you want to find the coordinates.
- Move your cursor or finger to the desired point on the graph.
- As you move the cursor or finger, you will notice a small crosshair or dot following your movement on the graph.
- Pay attention to the numbers displayed on the x-axis and y-axis near the cursor or dot. These numbers represent the coordinates of the point on the graph.
- The number displayed along the x-axis corresponds to the x-coordinate of the point.
- The number displayed along the y-axis corresponds to the y-coordinate of the point.

- Read the x-coordinate and y-coordinate values from the x-axis and y-axis, respectively, near the cursor or dot to determine the coordinates of the point.
- You can write down or use these coordinates for further calculations or analysis.

By following these steps, you can find the coordinates of a point on a graph using Desmos by observing the values displayed on the x-axis and y-axis near the cursor or dot as you move it across the graph.

#### What is the XY coordinate of a graph?

The XY coordinate of a graph refers to a pair of numbers that represent the position of a point on the graph. The X-coordinate represents the horizontal position of the point along the x-axis, and the Y-coordinate represents the vertical position of the point along the y-axis.

In a Cartesian coordinate system, the x-axis and y-axis intersect at a point called the origin, typically denoted as (0, 0). The X-coordinate of a point represents its horizontal distance from the origin, with positive values to the right of the origin and negative values to the left. The Y-coordinate represents the vertical distance from the origin, with positive values above the origin and negative values below.

For example, in the coordinate (3, 2), the X-coordinate is 3, indicating that the point is three units to the right of the origin, and the Y-coordinate is 2, indicating that the point is two units above the origin. The XY coordinates allow us to precisely locate and describe points on a graph or in a coordinate system.
