CALCULATE: Linear Patterns
The pattern below represents a linear function because it grows at a constant rate. Study the pattern below to write an equation that models the function.
How many squares will be in the 6th figure?
Describe the pattern.
How many squares are in figure zero?
Write an equation to model the number of squares, y, that are in figure x.
Linear Equations in Slope-Intercept Form
When something changes at a constant rate, like the pattern from the intro activity above, we can write a linear equation to model how it changes. In this activity, you’ll learn how to write linear equations using one form called slope-intercept form. Follow your teacher’s instructions to review the formula below and practice writing linear equations.
