Relationships in Two Variables

Front

What is a coordinate point?

Back

A coordinate point is a pair of numbers that define a specific location on a graph, represented as (x, y).

Front

What does the x-axis represent on a graph?

Back

The x-axis represents the independent variable in a graph.

Front

What does the y-axis represent on a graph?

Back

The y-axis represents the dependent variable in a graph.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to locate a point on a coordinate plane, written as (x, y).

Front

What is the equation of a line that passes through the origin and has a slope of 5?

Back

The equation is y = 5x.

Front

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

Back

Substitute the x-value into the equation and see if the resulting y-value matches the y-value of the point.

Front

What is a function?

Back

A function is a relationship where each input (x) has exactly one output (y).

Front

What is a table of values?

Back

A table of values lists pairs of x and y values that satisfy a particular equation.

Front

What does it mean for two variables to be related?

Back

Two variables are related if changes in one variable cause changes in the other variable.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the change in y divided by the change in x.
