Product description

From the author

This linear-functions worksheet set connects equations, slope, intercepts, points, tables and graphs. Charts A–H start from given information; chart I asks students to create a function.

The seventeen-page PDF contains nine student charts and eight answer charts. The key identifies cells where valid responses may vary.

Teaching tips & learning objectives

Learning objectives

  • Convert a linear equation between standard form, slope-intercept form, and point-slope form.

  • Determine the x-intercept, y-intercept, and slope of a line from any one of its given representations.

  • Construct an original linear function and represent it across all of these forms.

Teaching tips

  • Assign one or two functions per class period rather than all nine at once, since each chart requires working through six to seven interconnected representations for a single line.

  • Discuss with students why some chart cells are marked "Answers May Vary" (for example, when choosing two points on a line), so they understand multiple correct answers are possible rather than assuming they made an error.

  • Use Function I, "Create Your Own," as a formative check after the first eight functions, since it requires students to generate and represent a line themselves rather than transform a given one.

Skills covered

  • Form conversion — students rewrite a linear equation among standard form, slope-intercept form, and point-slope form starting from just one given form.

  • Slope and intercept identification — students determine a line's x-intercept, y-intercept, and slope from whichever representation is provided.

  • Function construction — in the "Create Your Own" chart, students invent a linear function and represent it across every format themselves.

Good to know

Questions teachers ask about this resource

Does every chart give the same type of starting information?

No — some functions start from standard form (2x - 4y = 12), others from point-slope form, and others from just a y-intercept and slope, so students practice working forward from different starting representations.

What is Function I asking students to do?

Function I, "Create Your Own," leaves every cell blank so students invent their own linear function and fill in all of its representations themselves, rather than transforming a function that's already given.
