Graphing Ordered Pairs

Front

What is the Y-axis?

Back

The Y-axis is the vertical line on a graph that represents the dependent variable.

Front

What is the X-axis?

Back

The X-axis is the horizontal line on a graph that represents the independent variable.

Front

What does an ordered pair represent?

Back

An ordered pair (x, y) represents a point on a graph where 'x' is the value on the X-axis and 'y' is the value on the Y-axis.

Front

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

Back

Substitute the 'x' value into the equation and see if the resulting 'y' value matches the 'y' in the ordered pair.

Front

What does the ordered pair (3, 2) mean?

Back

It means that when 'x' is 3, 'y' is 2 on the graph.

Front

What is the distance formula?

Back

The distance formula is used to determine the distance between two points (x1, y1) and (x2, y2) and is given by: d = √((x2 - x1)² + (y2 - y1)²).

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness and is calculated as the change in 'y' divided by the change in 'x' (rise/run).

Front

What does it mean if a line is horizontal?

Back

A horizontal line has a slope of 0 and runs parallel to the X-axis.

Front

What does it mean if a line is vertical?

Back

A vertical line has an undefined slope and runs parallel to the Y-axis.

Front

What is a graph?

Back

A graph is a visual representation of data that shows the relationship between two variables.
