• 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
