What is a linear equation?

Back

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of the dependent variable (y) with respect to the independent variable (x). It indicates how steep the line is.

Front

How do you find the intersection of two linear equations?

Back

To find the intersection of two linear equations, solve the system of equations simultaneously, either by substitution or elimination methods.

Front

What is the y-intercept of a linear equation?

Back

Front

What does it mean for a function to have three real roots?

Back

A function has three real roots if it intersects the x-axis at three distinct points, indicating that the function changes sign three times.

Front

What is a scatterplot?

Back

A scatterplot is a graphical representation of two variables, showing the relationship between them using points on a Cartesian plane.

Front

What is the purpose of a linear model?

Back

A linear model is used to describe the relationship between two variables by fitting a straight line to the data points, allowing for predictions.

Front

What is the general form of a cubic function?

Back

Front

How can you determine the number of solutions to a system of equations?

Back

The number of solutions to a system of equations can be determined by analyzing the graphs of the equations: no solution (parallel lines), one solution (intersecting lines), or infinitely many solutions (same line).

Front

What is the significance of the coefficients in a polynomial function?

Back

The coefficients in a polynomial function determine the shape and position of the graph, influencing the function's behavior and roots.
