Chapter 6 Section 3 Slope Essential Question •How do we use rate of change in real-world applications? Different Kinds of Slope How to find slope •Solve for y so that the equation is y = mx + b and m is the slope •M = (y2 – y1) = (x2 – x1) for 2 given points (x1, y1) and (x2, y2) •Practice: •(3, 4) and (8, 6) •(3, -7) and (-1, 5) Rate of Change •The tuition in 2006 was $2,554 and in 2007 was $2,649. What is the rate of change? •The equation P = 223,500 +174F describes the relationship between the price of a home P in dollars and its number of square feet of space F. What does slope mean here? What does the y-intercept mean here?
