Distance On A Coordinate Plane Worksheet: Easy Practice Guide
Table of Contents :
Distance on a coordinate plane is a fundamental concept in mathematics, particularly in geometry and algebra. Whether you’re a student trying to grasp the basics or a teacher looking for effective ways to teach this important concept, understanding how to calculate distance between points can be a significant stepping stone in your math journey. In this easy practice guide, we’ll explore the distance formula, provide examples, and even include a helpful worksheet to reinforce your understanding.
Understanding the Coordinate Plane 🗺️
Before we dive into calculating distance, let's quickly recap what a coordinate plane is. A coordinate plane consists of two perpendicular lines, the x-axis (horizontal) and the y-axis (vertical), which intersect at a point known as the origin (0, 0). Points on this plane are represented by ordered pairs (x, y), where "x" indicates the position along the x-axis and "y" indicates the position along the y-axis.
The Distance Formula 📏
The distance between two points on a coordinate plane can be calculated using the Distance Formula. The formula is derived from the Pythagorean theorem and is expressed as follows:
[ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} ]
Where:
- (d) is the distance between the two points.
- ((x_1, y_1)) and ((x_2, y_2)) are the coordinates of the two points.
Example Calculations 🔍
Let's illustrate how to use the distance formula with a couple of examples.
Example 1
Calculate the distance between the points (2, 3) and (5, 7).
Solution:
- Identify the coordinates: ((x_1, y_1) = (2, 3)) and ((x_2, y_2) = (5, 7)).
- Plug the values into the distance formula:
[ d = \sqrt{(5 - 2)^2 + (7 - 3)^2} ]
[ d = \sqrt{(3)^2 + (4)^2} ]
[ d = \sqrt{9 + 16} = \sqrt{25} = 5 ]
The distance between the two points is 5 units. 🎉
Example 2
Calculate the distance between the points (-1, -2) and (3, 4).
Solution:
- Identify the coordinates: ((x_1, y_1) = (-1, -2)) and ((x_2, y_2) = (3, 4)).
- Plug the values into the distance formula:
[ d = \sqrt{(3 - (-1))^2 + (4 - (-2))^2} ]
[ d = \sqrt{(4)^2 + (6)^2} ]
[ d = \sqrt{16 + 36} = \sqrt{52} \approx 7.21 ]
The distance between the two points is approximately 7.21 units. 🌟
