# Inverse relationship between x and y graph

### What are the different types of mathematical relationships? Below is a graph of data relating Specific Crushing Strength with Pressure (P). Inverse Relationship. Now, let's look at the following equation: Y = 1/X. If X=1. X = 4? Now look at a graph of how Y varies as we change X. As X increases in magnitude, Y increases in a linear fashion. This is called a direct relationship. This graph states, therefore, that A is inversely proportional to B. (It also states that B is inversely proportional The point is (B1, A1) and it has coordinates (1, 1 ).

Graphing Inverse Relations

Using the example from the last section, the higher from which you drop a ball, the higher it bounces back up. A circle with a bigger diameter will have a bigger circumference. If you increase the independent variable x, such as the diameter of the circle or the height of the ball dropthe dependent variable increases too and vice-versa. Sciencing Video Vault A direct relationship is linear.

Pi is always the same, so if you double the value of D, the value of C doubles too. The gradient of the graph tells you the value of the constant. Inverse Relationships Inverse relationships work differently. If you increase x, the value of y decreases. For example, if you move more quickly to your destination, your journey time will decrease.

In this example, x is your speed and y is the journey time. Doubling your speed halves the journey time, and increasing the speed by ten times makes the journey time ten times shorter.

Mathematically, this type of relationship has the form: As you start to increase x, y decreases really quickly, but as you continue increasing x the rate of decrease of y gets slower. In this case, y is inversely related to x.

At first an increase of 3 in x decreases y by 2, but then an increase of 6 in x only decreases y by 1. This is why inverse relationships are declining curves that get shallower the further you move along them. If we plot the X-y graph a straight line will be formed.

In nature data is not exact so points will not always fall on the line. The points fall close enough to the straight line to conclude that this is a linear or direct relationship. What are independent and dependent variables in the graph? Independent variable -An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. It is something that depends on other factors. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it.

Usually when you are looking for a relationship between two things you are trying to find out what makes the dependent variable change the way it does. Inverse Relationship Now, let's look at the following equation: Note that as X increases Y decreases in a non-linear fashion. This is an inverse relationship.

## Inverse Proportion and The Hyperbola Graph

Example of an inverse relationship in science: When a higher viscosity leads to a decreased flow rate, the relationship between viscosity and flow rate is inverse. Inverse relationships follow a hyperbolic pattern. Below is a graph that shows the hyperbolic shape of an inverse relationship. Quadratic formulas are often used to calculate the height of falling rocks, shooting projectiles or kicked balls.

A quadratic formula is sometimes called a second degree formula.

Quadratic relationships are found in all accelerating objects e. Below is a graph that demostrates the shape of a quadratic equation. Inverse Square Law The principle in physics that the effect of certain forces, such as light, sound, and gravity, on an object varies by the inverse square of the distance between the object and the source of the force.

In physics, an inverse-square law is any physical law stating that a specified physical quantity or intensity is inversely proportional to the square of the distance from the source of that physical quantity. The fundamental cause for this can be understood as geometric dilution corresponding to point-source radiation into three-dimensional space. One of the famous inverse square laws relates to the attraction of two masses.

Two masses at a given distance place equal and opposite forces of attraction on one another. The magnitude of this force of attraction is given by:
