Y-intercept and Equation of a Line (y=mx+b)
Students will identify the y-intercept and write the equation of a line in slope-intercept form.
Key Questions
- Explain the significance of the y-intercept as the initial value in a linear model.
- Construct the equation of a line given its slope and y-intercept.
- Analyze how changes in 'm' or 'b' affect the graph of a linear equation.

Planning templates for Mathematics
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
unit plannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
rubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.
