Instructions for lesson delivery
• This is part 2 for the lessons on linear equations
• Print out the last page for each students so they can place them in their whiteboards.
• The independent practice is on edusoft
Today we will determine the rule of a Linear
EquationsGraph = a visual of a set of
ordered pairs on a grid
APK ( Work with your partner)x Y = x + 1 y (x , y)y = x + 1
1. Choose 3 values for “x” and place them in a table.
2. Find solutions using table
3. Graph the points from the table
4. Draw a line to connect them

The Rule of Linear EquationIs the relationship between the two
variables in an equation
Example:
y = x + 2
Why is this important?
• You can use this to solve real life problems (For example, when you are adding and subtracting from your bank account constantly)
• This will help you with algebra
• You HAVE to know algebra to get into college.
Finding the Rulex y (x , y)
1. Identify the ordered pairs of the dots on the line and place it in a table
2. Find the rule by figuring out what happened to X to get Y
3. Make sure the rule applies to all ordered pairs
4. Write the rule for identifying Y
