A line on a graph that compares two variables, temperature for example tells us a great deal about the relationship of these variables in the experimental system. When the line is straight it reflects a direct and proportional relationship between the two factors.
A straight line on a graph usually indicates a linear relationship between two variables, in this case, two temperatures. The slope of the line can tell us the rate of change between the two temperatures. If the line has a positive slope, it means the temperatures are positively correlated, while a negative slope indicates a negative correlation.
If your data doesn't graph into a straight line, it may suggest a nonlinear relationship between the variables. In such cases, you can try fitting a curve or using a different type of regression analysis, such as polynomial regression or exponential regression, to better capture the underlying relationship in your data. It's important to choose the appropriate model that best fits your data and the underlying theory.
Ejnar Hertzsprung and Henry Norris Russell,working independently, realized the relationship between a star's temperature and its brightness.Together, in 1910, they formed what is now known as the Hertzsprung--Russell diagram or HR Diagram.It's a scatter graph showing the relationship between a star's absolute magnitudes, their spectral types and temperatures.
A scatter plot is most useful for showing the relationship between two numerical values. It can reveal patterns such as correlations, clusters, or trends in the data.
The relationship in Charles's law is a direct relationship between the volume and temperature of a gas at constant pressure. As temperature increases, the volume of the gas also increases, and vice versa. This relationship is shown as a straight line when graphed.
A line graph would be best to show high and low temperatures for a week as it can clearly display the trend over time and easily highlight the differences between the high and low temperatures on each day.
Linear = Straight line! So, a graph of a linear relationship is a straight line.
_linear_
_linear_
it is a positive relationship
The graph is a straight line.
Straight line.
A linear relationship will show up on a graph as a straight line.
By definition, if you graph the relationship between two variables and the result is a straight line (of whatever slope) that is a linear relationship. If it is a curve, rather than a straight line, then it is not linear.
