What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship between two quantitative variables by displaying data points on a two-dimensional grid.

Front

What is the line of best fit?

Back

The line of best fit is a straight line that best represents the data on a scatter plot, used to predict values.

Front

How do you write a linear equation in function notation?

Back

A linear equation in function notation is written as f(x) = mx + b, where m is the slope and b is the y-intercept.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and will never intersect.

Front

How do you simplify a radical expression?

Back

To simplify a radical expression, factor the number under the radical into its prime factors and extract any perfect squares.

Front

What is a system of inequalities?

Back

A system of inequalities is a set of two or more inequalities with the same variables, representing a region on a graph.

Front

What is the solution to a system of inequalities?

Back

The solution to a system of inequalities is the set of all points that satisfy all inequalities in the system.

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you determine if a point is a solution to an inequality?

Back

To determine if a point is a solution to an inequality, substitute the point's coordinates into the inequality and check if the statement is true.

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input (x-value) has exactly one output (y-value).
