What is a unit rate?

Back

A unit rate is a ratio that compares a quantity to one unit of another quantity, often expressed as 'x per 1 unit'.

Front

How do you determine the unit rate from a graph?

Back

To determine the unit rate from a graph, find the slope of the line, which represents the change in the dependent variable for each unit change in the independent variable.

Front

What does a nonlinear scatterplot indicate?

Back

A nonlinear scatterplot indicates that the relationship between the variables does not follow a straight line, suggesting a more complex relationship.

If Joe earned $400 for 25 hours of work, what is his hourly wage?

Back

His hourly wage is $16 per hour, calculated by dividing $400 by 25 hours.

Front

What is the significance of the slope in a graph?

Back

The slope of a graph indicates the rate of change between the two variables represented, showing how much one variable changes in relation to another.

Front

How can you estimate values from a graph?

Back

You can estimate values from a graph by locating the point on the graph that corresponds to the given input and reading the output value directly.

Front

What is the formula for calculating the slope of a line?

Back

The formula for calculating the slope (m) is m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.

Front

What does it mean if a graph is scattered?

Back

A scattered graph indicates that there is no clear pattern or relationship between the variables, with points spread out across the graph.

Front

How do you interpret a scatterplot?

Back

To interpret a scatterplot, look for trends, clusters, or outliers in the data points to understand the relationship between the two variables.

What is the relationship between temperature and lemonade sales based on a graph?

Back

The relationship can often be positive, indicating that as temperature increases, lemonade sales also tend to increase.
