Respuesta :
A proportional relationship is a relationship between two equal ratios. So using a graph and an x/y table would be very useful in figuring that out because it describes the difference between x and y.
Proportional relationships are used to relate variables that have equivalent ratios.
Using tables
Assume the variables are x and y.
To make use of tables, then the values of x and y must change at a constant rate.
Take for instance, the following table of values
x: 1, 2, 3
y: 2, 4, 6
Notice that, as x increases by 1; y increases by 2.
Such relationship is a proportional relationship
Using equations
A proportional relationship is represented by the following equation
[tex]\mathbf{y = kx}[/tex]
Where k represents the proportionality constant, and k is not equal to 0
An example of such equation is [tex]\mathbf{y = 2x}[/tex]
Using graphs
The graph of a proportional relationship is simply a straight line that passes through the origin, and does not have an undefined slope or a slope of 0
See attachment for a graph that represents a proportional relationship.
