Slope Intercept Form The slope will describe the rate of change. The intercept will describe the data when x = 0. The equation that describes the work we have done in this component, written in slope intercept form, is y = 2x + 1. y = 1 + 2x 1 Linear Algebra

1 Relationship between the stage number Number of counters in equation form 1 Linear Algebra A function, like an equation, describes a relationships between sets of data. A function assigns each value of the independent variable (x) to only one value of the dependent variable (y). The function that describes Maria’s work would be f(x) = 2x + 1. If the value of x is 3, the function tells us that f(3) = = 7. Function notation Slope Intercept Form The slope will describe the rate of change The intercept will describe the data when x = 0. The equation that describes the work we have done in this component, written in slope intercept form, is y = 2x + 1.
