Mathematics
This Grade 8 mathematics worksheet helps students write linear equations in slope-intercept form, y = mx + b, when the slope (m) and y-intercept (b) are given. Across 8 multiple-choice questions, students identify where each value belongs, preserve positive or negative signs, and select the equation that matches the stated slope and y-intercept. Examples include equations with zero, positive, and negative intercepts and slopes, as well as a slope of 1. Use this free printable worksheet for guided practice, independent work, homework, or a quick check of students’ ability to connect slope-intercept vocabulary to an equation. The answer choices make common errors visible, such as switching m and b or changing the sign of the intercept. It includes a complete answer key for efficient checking and feedback, and the worksheet is also available digitally through Wayground.

This Grade 8 worksheet focuses on writing equations in slope-intercept form, y = mx + b, when m and b are provided. Its 8 multiple-choice items require students to place the given slope as the coefficient of x and the y-intercept as the constant, including cases with zero and negative values. Comparing the options helps students recognize sign and placement errors.
Begin by reviewing y = mx + b and have students label m as the slope and b as the y-intercept. Model one item by substituting the given values, then ask students to explain why distractors such as y = 3x + 2 reverse the roles of slope and intercept. Use the remaining multiple-choice questions for guided practice, asking students to justify the sign of each term before selecting an answer.
Watch for students switching the slope and y-intercept, as in choosing 3x + 2 when the slope is 2 and the intercept is 3. Students may also reverse a negative sign, write a positive constant for a negative intercept, or choose the wrong sign for a negative slope. The items with a zero intercept and a slope of 1 are useful checks that students understand y = -3x and y = x rather than treating omitted or simple values incorrectly.
You can assign this worksheet as a printable PDF or use it as a digital quiz on Wayground; it includes a complete answer key for all 8 multiple-choice questions. For printable submissions, scan student work with the Wayground for Teachers app to support faster grading and review of errors in placing m and b.
Use the worksheet’s Advanced Settings to adjust font spacing or choose a larger font size so the equation choices are easier to read and compare. You can also enable a dyslexia-friendly font or translate the worksheet into another language when those options support students working through the slope-intercept questions.
