What does a scatterplot represent in data analysis?

Back

A scatterplot is a graphical representation that shows the relationship between two quantitative variables, with points plotted on a Cartesian plane.

What is the purpose of using variables in algebra?

Back

Variables are used to represent unknown values and allow for the formulation of equations and expressions.

Front

What is the difference between an equation and an expression?

Back

An equation states that two expressions are equal, while an expression is a combination of numbers, variables, and operations without an equality sign.

Front

How do you isolate a variable in an equation?

Back

To isolate a variable, perform inverse operations to both sides of the equation until the variable is alone on one side.

What does it mean to graph a linear equation?

Back

Graphing a linear equation involves plotting points that satisfy the equation on a coordinate plane, resulting in a straight line.
