## Which Expression Represents the Distance Between Point (0, a) and Point (a, 0) on a Coordinate Grid?

Have you ever wondered about the distance between two points on a coordinate grid? Specifically, what expression represents the distance between point (0, a) and point (a, 0)? It may seem perplexing at first, but I’ll shed some light on this topic for you.

To find the distance between these two points, we can use the Pythagorean theorem. This theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. In this case, our two sides are represented by “a” units each. By applying this theorem to our coordinates (0, a) and (a, 0), we can determine that the distance is √(a^2 + a^2).

In simpler terms, we can say that the distance between point (0, a) and point (a, 0) is equal to √(2a^2). By understanding this expression and how it relates to coordinate grids, you’ll have a better grasp on calculating distances between points in Cartesian coordinates.

So now you know how to find the distance between these two specific points on a coordinate grid using an expression derived from the Pythagorean theorem. Keep in mind that this method applies specifically to these coordinates – for different sets of points or shapes on a grid, alternative formulas might be required. Stay tuned for more insights into mathematical concepts like these!

## Understanding the Coordinate Grid

Let’s delve into the fundamental concept of the coordinate grid. The coordinate grid, also known as the Cartesian plane, is a two-dimensional system used to represent points in space. It consists of two perpendicular lines, the x-axis (horizontal) and the y-axis (vertical), intersecting at a point called the origin.

The x-axis represents horizontal movement and is labeled with positive numbers to the right of the origin and negative numbers to the left. On the other hand, the y-axis represents vertical movement and is labeled with positive numbers above the origin and negative numbers below.

To locate a specific point on this grid, we use ordered pairs in the form (x, y). The first value denotes its position on the x-axis, while the second value indicates its position on the y-axis. For example, if we have a point located at (3, 2), it means that it is three units to the right of the origin along x-axis and two units above along y-axis.Navigating through this grid allows us to perform various calculations and determine distances between points. In our case specifically, we are interested in finding out which expression represents distance between point (0,a) and point (a,0)By applying basic principles of geometry or Pythagorean theorem specifically, we can find that this distance corresponds to √(a^2 + a^2), which simplifies to √(2a^2). So if you encounter such an expression when dealing with distances on a coordinate grid involving these particular points, you now know how it relates!

Understanding how points are represented on a coordinate grid provides us with insights into their positions relative to each other. By grasping this concept thoroughly, we gain valuable skills for solving problems involving distances between points or even plotting graphs.
