Answer:
An equation is basically a way to show a relationship of variables (x,y,a,b, etc) and numbers. The relationship between these numbers and variables is a lot like a laundry bag. ... The amount of shirts and pants in each of those laundry bags could be counted separately, or if you combine them, counted together
An equation is distinct because it has an equals sign, and that in itself creates a relationship. Usually, it's relating the left side to the right side in terms of that fact that they're equal to each other- unlike inequalities which form more of a relation between two quantities that can be greater than or less than.
Scatterplot is a type of data display that shows the relationship between two numerical variables. Each member of the dataset gets plotted as a point whose x-y coordinates relates to its values for the two variables.A formula is an equation that expresses a relationship between two or more variables.
The process of finding formulas to describe real-world phenomena is called mathematical modeling. Such formula are often called mathematical models (or just models).
