To determine the meaning of the point (9, 90), we need to know the context or the relationship being described. However, based on the format of your question, we can infer a general interpretation related to proportional relationships, commonly seen in math.
(9, 90):
-
9 represents: This value can be interpreted as the independent variable (often the input or the 'x' value). For example, if we are discussing a situation where 9 represents a quantity like hours worked, students in a class, or any other measure that leads to a total.
-
90 represents: This value is typically the dependent variable (often the output or the 'y' value). In this context, it could represent a total such as total money earned, total distance traveled, or another measure related to the first value (9).
Question 2: Regarding the constant of proportionality, this often represents the ratio between the dependent and independent variable in a proportional relationship. The point for the constant of proportionality can be determined from the equation \( y = kx \), where \( k \) is the constant of proportionality.
From the point (9, 90), we calculate the constant of proportionality \( k \) as follows:
-
Use the relationship \( k = \frac{y}{x} = \frac{90}{9} = 10 \)
-
Therefore, the constant of proportionality \( k \) is 10.
The point representing the constant of proportionality would be:
(1, 10)
This means that for every 1 unit increase in 9 (the independent variable), there is a corresponding increase of 10 in 90 (the dependent variable).
