How do you explain a scatter plot?

A scatter plot (aka scatter chart, scatter graph) uses dots to represent values for two different numeric variables. The position of each dot on the horizontal and vertical axis indicates values for an individual data point. Scatter plots are used to observe relationships between variables.

How do you know if a scatter plot is linear?

Notice that starting with the most negative values of X, as X increases, Y at first decreases; then as X continues to increase, Y increases. The graph clearly shows that the slope is continually changing; it isn’t a constant. With a linear relationship, the slope never changes.

How do you plot points in R?

To add new points to an existing plot, use the points() function. The points function has many similar arguments to the plot() function, like x (for the x-coordinates), y (for the y-coordinates), and parameters like col (border color), cex (point size), and pch (symbol type).
