Graph Ratio Tables

Front

What is a ratio table?

Back

A ratio table is a table that shows the relationship between two quantities, displaying pairs of numbers that maintain a constant ratio.

Front

What does an ordered pair represent in a coordinate plane?

Back

An ordered pair represents a specific point in a coordinate plane, defined by its horizontal (x) and vertical (y) positions.

Front

What is the purpose of the x-axis in a coordinate plane?

Back

The x-axis is the horizontal line in a coordinate plane where the y-coordinate is zero.

Front

What is the purpose of the y-axis in a coordinate plane?

Back

The y-axis is the vertical line in a coordinate plane where the x-coordinate is zero.

Front

How do you identify a point on a graph?

Back

A point on a graph is identified by its coordinates, written as (x,y), where x is the value on the x-axis and y is the value on the y-axis.

Front

What does it mean for two quantities to be in a proportional relationship?

Back

Two quantities are in a proportional relationship if they maintain a constant ratio or rate.

Front

How can you determine the slope of a line on a graph?

Back

The slope of a line is determined by the rise over run, calculated as the change in y divided by the change in x between two points on the line.

Front

What is the significance of the origin in a coordinate plane?

Back

The origin is the point (0,0) in a coordinate plane where the x-axis and y-axis intersect.

Front

What does it mean for a graph to be linear?

Back

A graph is linear if it forms a straight line, indicating a constant rate of change between the variables.

Front

How do you plot a point on a graph?

Back

To plot a point, start at the origin, move horizontally to the x-coordinate, and then vertically to the y-coordinate.
