Because the value of y depends on the value of x, it should be plotted against the value of x, not the other way around. y is a case where the value of y depends on the value of x, so this is the case.
From a mathematical point of view, it doesn’t matter as long as your equations and data are the same. The usual way to do this is to write y as a function of x or, if you prefer, as a relative comparison to x. There’s no reason why x and y couldn’t be switched around whenever someone wanted to. That’s a real possibility. Because that’s the way things work.
Axis labels are the words that are used to show the major divisions in a chart. On the category axis are the names of the categories, and on the value axis are the values. I agree with the rule about who is dependent and who is not. When the phrase “compared with” means “against,” it usually makes the most sense to compare a dependent value to the independent value that is linked to that dependent value. A dependent variable doesn’t “care” about an independent variable, so when they are both in an equation, this is what happens.
It’s hard to understand what it means to plot A against B.
When graphs are needed for the lab exercises in this book, you will be told to “plot A versus B.” (where A and B are variables). Since it’s common to plot variables along axes, it’s common to plot dependent variables (A) along the ordinate and independent variables (B) along the horizontal axes (abscissa).
To start your investigation, choose two points on the line where you want to pay the most attention.
In this section, please tell us the difference between the two points’ y-coordinates (rise).Use the following notation to write a linear equation: The line’s slope and its y-intercept are connected in some way. This formula works for any straight line. The value of y at the point where a line crosses the y-axis is called its y-intercept.
In linear regression analysis, it seems like the constant term is a very simple idea. It is the point where the fitted line crosses the y-axis. It is also known as the y intercept. Even though the constant term doesn’t have much importance most of the time, it’s important to include it in most regression models.

Because of this plan, the intercept isn’t always a big deal. The mean is useful if every X in the model has at least one value of zero. This is the case because the intercept equals the mean of Y when all the predictors are equal to zero. So, the intercept must be used when figuring out predicted values, even though it is useless on its own.
