What determine from the graphs of a system of two equations in two variables?
The graphs of a system of two equations in two variables can determine the solutions to the system. If the graphs intersect at a single point, that point represents the unique solution. If the graphs are parallel and do not intersect, the system has no solution (inconsistent). If the graphs coincide, there are infinitely many solutions (dependent).
What graph shows realationships between two variables?
The vast majority of all graphs do that.
What are proportional relationships in graphs?
Proportional relationships in graphs are represented by straight lines that pass through the origin (0,0). In these relationships, the ratio of the two quantities remains constant, meaning that as one quantity increases or decreases, the other does so in a consistent manner. This can be visually identified by the slope of the line, which represents the constant ratio. Overall, proportional relationships illustrate a direct correlation between two variables.
Which graph shows independent variable on the y axis?
Graphs showing the relationship (or not) between two independent variables.
What graphs is often used for showing association between two variables?
None of the items on that list can show that association.
Quantitative variables use which two levels of measurement?
Interval and ratio
Quantitative variables can be separated into what two types?
nominal and ordinal is wrong; those are the two types of qualitative variables. Ratio and interval are the two types of quantitative variables.
If two graphs have exactly the same shape what can you tell about the variables?
If two graphs have exactly the same shape, it indicates that the variables are proportional to each other. This means that as one variable increases or decreases, the other variable changes in a consistent and fixed ratio.
What Bar graphs are similar to line graphs because they both?
Represent two variables on two axes.
What determine from the graphs of a system of two equations in two variables?
The graphs of a system of two equations in two variables can determine the solutions to the system. If the graphs intersect at a single point, that point represents the unique solution. If the graphs are parallel and do not intersect, the system has no solution (inconsistent). If the graphs coincide, there are infinitely many solutions (dependent).
What are the two variables that line graphs display?
x and y
In what way are line graphs similar to bar graphs?
They illustrate the relationship between two (or more) variables.
What is the ratio of two variables called?
Quotient.

What is a comparison of two of two numbers or variables that can be written in fraction form?
It is a ratio.

None of the items on that list can show that association.
