Lesson 13.6 – Writing Equations in SlopeIntercept Form 8.F.4 – Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of a linear function in terms of its graph or a table of values. Warm-Up Find the slope of the line. Today you will learn… to write an equation of a line in slope-intercept form. a. find slope b. y-intercept y = mx + b On Your Own Extra Example Write an equation of the line that passes through the points (0, -1) and (4, -1). On Your Own Mini-Assessment Exit Ticket Writing Prompt: For a line that has been graphed in a coordinate plane, you can write the equation by… Find the slope and y-intercept Homework pp. 606 – 607 1 – 4, 6 – 10 even, 11 - 24
