Free Printable Intercepts Worksheets for Class 9

In 9th grade Algebra 1, the concept is formalized and expanded. Students solidify finding intercepts for linear functions and are formally introduced to the term 'zero of a function' as a synonym for the x-intercept. This prepares them to find intercepts of non-linear functions, like quadratics.

Explain that these terms ask the same question in different ways. 'Find the x-intercept' is a graphical question: Where does the graph cross the x-axis? 'Find the zeros' is an algebraic question: What input value of x makes the function's output, f(x), equal to zero? Showing they yield the same result helps students connect the vocabulary to the concept.

A strong 9th-grade worksheet will review finding intercepts for linear equations in all forms while using the formal vocabulary of 'zeros.' It should also begin to introduce finding intercepts for simple quadratic functions, which sets the stage for more advanced function analysis.

Students can be confused by the multiple terms used for the same concept: x-intercept, zero, root, and solution. It is important to explicitly teach that these terms are often used interchangeably to describe the x-value where a function's graph intersects the x-axis.

Assign the worksheet as a printable PDF for focused, off-screen practice, and use the Wayground for Teachers app to quickly scan and grade student work. Alternatively, you can host it as a digital quiz on the Wayground platform. A full answer key is provided for both formats.

Under the Common Core State Standards for high school algebra, finding and interpreting intercepts is a critical part of analyzing functions. It directly relates to understanding the relationship between the zeros of a function, the factors of a polynomial, and the solutions of an equation (HSA-IF.C.7).
