Investigation 1 and 2 Review [Variables and Patterns]

Front

What is a variable in an experiment?

Back

A variable is any factor, trait, or condition that can exist in differing amounts or types. In an experiment, variables are what you measure and manipulate.

Front

What is a constant in an experiment?

Back

A constant is a factor that remains the same throughout an experiment, ensuring that the test results are valid.

Front

What does it mean for a relationship to be linear?

Back

A linear relationship means that as one variable increases or decreases, the other variable does so at a constant rate, forming a straight line when graphed.

Front

What is a graph?

Back

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

Front

What is the slope of a line?

Back

The slope of a line is a measure of how steep the line is, calculated as the change in the vertical direction (rise) divided by the change in the horizontal direction (run).

Front

How do you find the cost per pound from a total cost?

Back

To find the cost per pound, divide the total cost by the number of pounds.

Front

What does it mean when the cost per pound decreases as the number of pounds increases?

Back

It means that buying in bulk is cheaper, indicating a discount for purchasing more.

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 in a graph?

Back

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

Front

What does the y-axis represent in a graph?

Back

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