The equation ( y = 13x ) does represent a proportional relationship between ( x ) and ( y ). In this equation, ( y ) is directly proportional to ( x ) with a constant of proportionality equal to 13. This means that if ( x ) increases or decreases, ( y ) will change by the same factor, maintaining a constant ratio of ( \frac{y}{x} = 13 ).
A graph shows a proportional relationship when it displays a straight line that passes through the origin (0,0). This indicates that as one variable increases or decreases, the other variable does so at a constant rate. The slope of the line represents the constant ratio between the two variables, confirming their proportionality. If the line is not straight or does not pass through the origin, the relationship is not proportional.
Line graph is used to show relationship between two variables.
A scatterplot, if the relationship is inexact - like height and weight. A line graph for exact relationships. An equation or function may be used for exact relationships.
An equation represents the relationship between variables by expressing how one quantity depends on others through mathematical relationships. For example, in the equation (y = mx + b), (y) is dependent on the variable (x), with (m) representing the slope and (b) the y-intercept. This relationship allows us to predict the value of (y) based on different values of (x), illustrating how changes in one variable affect another. Thus, equations serve as a concise way to model and analyze relationships in various situations.
A function.
The relationship between the Kelvin and Celsius scales is given by the equation: [Kelvin = Celsius + 273.15] This equation shows how to convert temperature values between the two scales.
This representation is a chemical equation.
