Linear Relations Table
1. **Problem Statement:** Develop a lesson plan for Basic 9 on the indicator B9.2.1.1.1: Constructing a table of values for two linear relations and graphing these relations.
2. **Starter Activities:**
- Begin with a brief discussion about what linear relations are.
- Show simple examples of linear equations like $y=2x+1$ and $y=-x+3$.
- Ask learners to predict the values of $y$ for given $x$ values.
3. **Main Activities:**
- Guide learners to create tables of values for two given linear relations, e.g. $y=2x+1$ and $y=-x+3$ for $x$ values from $-2$ to $2$.
- Learners fill the tables by substituting each $x$ value into the equations.
- Plot the points from the tables on graph paper or using graph software.
- Join points to reveal the straight lines representing each relation.
- Assessment: Have learners construct their own tables and plot graphs for a new pair of linear relations independently.
4. **Reflection Activities:**
- Facilitate a brief discussion on how constructing tables helps in understanding the shape and position of linear graphs.
- Ask learners how graphing multiple relations can show their intersections or relative positions.
5. **Keywords:**
- Linear relation
- Table of values

7. **Core Competencies:**
- Critical thinking through interpreting and constructing tables and graphs.
- Problem solving by plotting and analyzing linear relations.
