A scatter graph.
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.
If the line of best fit on a linear graph is horizontal, it indicates that there is no correlation between the variables being analyzed. This means that changes in the independent variable do not affect the dependent variable, suggesting a constant value for the dependent variable across different levels of the independent variable. Essentially, the relationship is flat, indicating stability or lack of influence.
line graph
An independent variable is a factor or condition in an experiment that is manipulated or changed by the researcher to observe its effect on a dependent variable. It is the presumed cause in a cause-and-effect relationship and is typically plotted on the x-axis of a graph. By altering the independent variable, researchers can assess how it influences the outcome of the study.
the dependent variable has one value and the independent variable has no value

The independent variable is what you are changing in the experiment to get varied results. The dependent variable is the result of what you have changed. So the dependent variable depends on the independent variable. For example, if you are experimenting with the effect of water on height of a plant, the different amounts of water that you give the plant is the independent variable. The height of the plant that you measure as the result of the water is the dependent variable.
An independent variable is a factor or condition in an experiment that is deliberately manipulated or changed by the researcher to observe its effect on a dependent variable. It is considered the "cause" in a cause-and-effect relationship, allowing researchers to test hypotheses and establish correlations. The independent variable is typically plotted on the x-axis in a graph.
A scatter plot is commonly used to show the relationship between dependent and independent variables. In this graph, individual data points represent observations, with the independent variable plotted on the x-axis and the dependent variable on the y-axis. This visual representation helps to identify trends, correlations, or patterns in the data. Additionally, a line of best fit may be added to illustrate the overall relationship.
A scatter plot is commonly used to show the relationship between dependent and independent variables. In this type of graph, individual data points are plotted on a Cartesian plane, with the independent variable typically represented on the x-axis and the dependent variable on the y-axis. This allows for the visualization of correlations or trends between the two variables. Additionally, a line of best fit can be added to illustrate the overall relationship.
Independent: The heat Dependent: The result
An independent variable is the factor that is manipulated or changed by the researcher in an experiment to observe its effect on the dependent variable. It is the variable that is thought to cause a change in the dependent variable.
