What is the rate of change in a linear equation?

Back

The rate of change in a linear equation is the slope, which indicates how much the dependent variable (y) changes for a unit change in the independent variable (x).

Front

How do you determine which linear equation has a greater rate of change?

Back

Compare the slopes of the equations. The equation with the larger slope has a greater rate of change.

Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

What does it mean if the domain of a graph is 'all real numbers'?

Back

It means that the function can accept any real number as an input.

Front

What is a line of best fit?

Back

A line of best fit is a straight line that best represents the data on a scatter plot, used to make predictions.

Front

Why is a line of best fit important in data analysis?

Back

It helps to identify trends in data and make predictions based on those trends.

Front

What is an initial value in a function?

Back

The initial value is the value of the function when the independent variable (x) is zero.

Front

How do you compare initial values of two functions?

Back

Evaluate both functions at x=0 and compare the resulting values.

Front

What is a sequence in mathematics?

Back

A sequence is an ordered list of numbers that follow a specific pattern or rule.

Front

How do you find the first term in a sequence?

Back

The first term is the initial value of the sequence, often denoted as a1.
