What is a rectangle coordinate system?

The rectangular coordinate system is also called the xy-plane or the ‘coordinate plane’. The horizontal number line is called the x-axis. The vertical number line is called the y-axis. The x-axis and the y-axis together form the rectangular coordinate system.

How many coordinates does a rectangle have?

A rectangle is similar to an ordinary rectangle (See Rectangle definition ) with the addition that its position on the coordinate plane is known. Each of the four vertices (corners) have known coordinates.

How do you find the area of coordinates?

By finding the product of a point’s x coordinate times the next point’s y coordinate, then subtracting the y coordinate of the first point times the x coordinate of the second coordinate and dividing by two, you will find the area of the polygon.

What are the main features of rectangular coordinate system?

Notice that the rectangular coordinate system consists of 4 quadrants, a horizontal axis, a vertical axis, and the origin. The horizontal axis is usually called the x–axis, and the vertical axis is usually called the y–axis. The origin is the point where the two axes cross.

How are rectangular coordinates used in real life?

The Cartesian coordinate plane of x and y works well with many simple situations in real life. For instance, if you are planning where to place different pieces of furniture in a room, you can draw a two-dimensional grid representing the room and use an appropriate unit of measurement.

Which are the features of a rectangular coordinate system?

How do you find the area and perimeter with coordinates?


  1. Plot the coordinates. The first number tells the x value while the second number is the y value.
  2. Connect the dots and identify the figure. The connected points show a square.
  3. Determine lengths.
  4. If a formula exists, use it to find the perimeter and the area.

What is the perimeter of the rectangle in the coordinate plane?

Step 3: The perimeter of a rectangle can be computed by adding four sides p=l+l+w+w p = l + l + w + w , or, in simpler terms, double the sum of the two adjacent sides.

How do you write coordinates in an equation?

How to Find the Equation of a Line from Two Points

  1. Find the slope using the slope formula.
  2. Use the slope and one of the points to solve for the y-intercept (b).
  3. Once you know the value for m and the value for b, you can plug these into the slope-intercept form of a line (y = mx + b) to get the equation for the line.

What is the importance of the rectangular coordinate system?

Use the rectangular coordinate system to uniquely identify points in a plane using ordered pairs (x, y). Ordered pairs indicate position relative to the origin. The x-coordinate indicates position to the left and right of the origin. The y-coordinate indicates position above or below the origin.
