Diameter and area of a circle. 2 times the diameter ==> 4 times the original area.
Length and area of a rectangle. 2 times the length ==> 4 times the original area.
Diameter and volume of a spherical balloon. 2 times the diameter ==> 8 times the original volume.
A proportional graph, typically represented as a straight line through the origin (0,0), demonstrates a constant ratio between two variables. The slope of the line indicates the rate of change or the constant of proportionality. In such graphs, if one variable doubles, the other variable also doubles, maintaining a linear relationship. Additionally, all points on the line represent equivalent ratios, confirming the proportional relationship.
To determine if a relationship is linear by examining the words used to describe the variables, look for terms that imply a constant rate of change, such as "proportional" or "directly related." If the description suggests that one variable increases or decreases consistently with the other, it indicates a linear relationship. Conversely, words indicating a non-constant or varying rate of change, like "exponential" or "quadratic," suggest a nonlinear relationship.
Two ratios that describe the same relationship are 1:2 and 2:4. Both ratios represent the same proportional relationship, as they can be simplified to the same fraction (1/2). This means that for every 1 part of one quantity, there are 2 parts of another, and for every 2 parts of the first quantity, there are 4 parts of the second. Thus, they convey the same comparative relationship between the two quantities.
You can describe it using words or in graph form.
To determine if a relationship is linear based on word descriptions, look for terms that indicate a constant rate of change, such as "increase by a fixed amount" or "decrease steadily." Phrases like "proportional to" or "directly related" suggest a linear relationship, while words indicating varying rates, such as "exponential," "quadratic," or "nonlinear," imply a non-linear relationship. Additionally, if the variables are described as having a direct correlation without fluctuations, that further supports a linear relationship.
For each of the following relationships, graph the proportional relationship between the two quantities, write the equation representing the relationship, and describe how the unit rate, or slope is represented on the graph.
A strange word used to describe an otherwise indescribable situation.
Force= mass x acceleration. Therefore: Force is directly proportional to acceleration.
R = V/I Therfore the resistance is proportional to the voltage and inversely proportional to the current.
The current drawn from a power source is directly proportional to the voltage of thesource, and inversely proportional to the resistance of the circuit between its terminals.There is no relationship between the current and the physical size of the source.
Words such as "proportional to" "increases as" "decreases as", usually give an indication of a linear relation. If there are words like "Square" "power" "inversely proportional" then most likely not linear.
Ideally you would want one of the phrases "directly proportional", "varies according to" or similar.
The relationship between two variables whose ration is a constant value is a directly proportional relationship. An example of this is the ideal gas law, PV = nRT. Pressure and volume are directly proportional to the number of molecules of an ideal gas present ad the temperature.

"When the pressure of a gas at constant temperature is increased, the volume of the gas decreases. When the pressure is decreased, the volume increases." More precisely, pressure is inversely proportional to volume.
