👉 Linearities are a type of graph that is defined by its shape. In other words, they can be described in terms of their slope and y-intercept. Linearities can be categorized as straight lines or curves depending on how steeply they rise or fall. Examples of linearities include the line segment from (0, 0) to (1, 1), the line segment from (-1, -2) to (1, 4), and so on.
