When the graph of best fit is a straight line, the relationship between the dependent and independent variables is linear. This indicates that as the independent variable changes, the dependent variable changes at a constant rate. In other words, a change in the independent variable results in a proportional change in the dependent variable. This linear relationship can often be expressed with the equation of a line, typically in the form (y = mx + b), where (m) is the slope and (b) is the y-intercept.

What type of graph is most useful for making predictions about dependent variables?

A regression graph is most useful for predicting dependent variables, as it shows the relationship between the independent and dependent variables, allowing for the prediction of future values.

What term describes the relationship in which the dependent and independent variables in a graph both increase?

The term that describes the relationship in which both the dependent and independent variables in a graph increase is called a "positive correlation." In a positively correlated relationship, as the independent variable increases, the dependent variable also tends to increase, indicating a direct relationship between the two. This is often represented by an upward-sloping line on a graph.


On a graph of two variables which is the variable that causes changes in the other?

The independent variable causes changes in the dependent variable; the dependent variable is contingent on the manipulations of the independent variable.


What are the differences between independent and dependent variables?

Independent variables are controlled or manipulated by the researcher to determine their effect on the dependent variable. Dependent variables, on the other hand, are the outcome or response that is measured in an experiment. The independent variable causes a change in the dependent variable.
