Page 2: Understanding Y-Intercepts

This page focuses on the practical identification of y-intercepts from graphs.

Example: Multiple graphs are shown demonstrating y-intercepts in different contexts:

  • A water level graph with y-intercept (0, 4.5)
  • An elevation graph with y-intercept (0, -10)
  • A distance-time graph showing initial positions

Highlight: The y-intercept represents the value of the dependent variable when the independent variable equals zero.

The page emphasizes how y-intercepts can be interpreted in real-world contexts, such as initial water levels or starting elevations.

Page 3: Using Slope Formula to Find Y-Intercepts

This page demonstrates using slope formula to find y-intercept through worked examples.

Example: A detailed worked example shows how to:

  1. Calculate slope using two points
  2. Use the slope formula with a known point
  3. Solve for the y-intercept value

Definition: The slope formula is written as m = (y₂ - y₁)/(x₂ - x₁), where (x₁,y₁) and (x₂,y₂) are points on the line.

The page includes verification steps to ensure students understand that different points will yield the same y-intercept.

Page 5: Slope-Intercept Form Applications

This page begins to connect slope and y-intercept concepts to writing complete linear equations.

Definition: The slope-intercept form y = mx + b combines both the slope (m) and y-intercept (b) to create a complete linear equation.

Highlight: The page emphasizes how understanding both slope and y-intercept allows for complete representation of linear relationships.

The content builds toward writing equations using real-world data and practical applications.

Writing Equations in Slope-Intercept Form

This section focuses on writing linear equations using slope and y-intercept.

Definition: Slope-intercept form (y = mx + b) uses the slope (m) and y-intercept (b) to define a linear equation.

Highlight: Both y = mx + b and y = b + mx are acceptable forms of slope-intercept form.

Example: Converting linear relationships from tables and points to slope-intercept form.
