Chapter 10: Math Notes

f(x) = x − 7. A line that has Δy = 3 and Δx = 0. 2-28. Which of the lines that you graphed in problem 2-27 represent a function? If the line does not represent a function, why not? 2-29. What happens to the slope when the slope triangles are different sizes? For example, the line at right has three different slope triangles drawn as shown. ................
