Bi-Weekly Practice Review Activity -11/21/2024

Front

What is a line of best fit?

Back

A line that best represents the data on a scatter plot, showing the trend of the data points.

Front

How do you determine the predicted value using a line of best fit?

Back

Substitute the given x-value into the equation of the line of best fit to find the corresponding y-value.

Front

What does the slope of a line represent in a linear equation?

Back

The slope indicates the rate of change of the dependent variable (y) with respect to the independent variable (x).

Front

What is the y-intercept in a linear equation?

Back

The y-intercept is the value of y when x is 0, representing where the line crosses the y-axis.

Front

What is the equation of a line in slope-intercept form?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

How can you find the solution to a system of linear equations graphically?

Back

The solution is the point where the two lines intersect on the graph.

Front

What does it mean for a graph to have one x-intercept and one y-intercept?

Back

It means the graph crosses the x-axis at one point and the y-axis at one point, indicating a linear relationship.

Front

What is the significance of the x-value in a linear equation?

Back

The x-value represents the independent variable, which is manipulated to observe changes in the dependent variable (y).

Front

How do you interpret the slope in a real-world context?

Back

The slope can represent a rate, such as speed or cost per unit, depending on the context of the variables.

Front

What is a scatter plot?

Back

A graph that displays values for two variables for a set of data, showing the relationship between them.
