Graphing Ratios

A ratio is a relationship between two numbers indicating how many times the first number contains the second.

To graph a ratio, plot the points that represent the ratio values on the x and y axes, then connect the points to visualize the relationship.

The x-axis is the horizontal axis of the coordinate plane, typically representing the independent variable.

The y-axis is the vertical axis of the coordinate plane, typically representing the dependent variable.

To determine the better buy, compare the cost per unit or the value received for the price paid.

The point (5,3) represents a specific location on the graph where the x-coordinate is 5 and the y-coordinate is 3.

Multiply the unit price by the number of items to find the total cost.

The formula for calculating a ratio is: Ratio = Part / Whole.

A simplified ratio means that the numbers have been reduced to their smallest whole number form.

Interpreting a graph showing ratios involves analyzing the slope and position of the plotted points to understand the relationship between the variables.
