deling with Mathematics In Exercises 21-26, write a linear function f with the -slope form and has given values. (See Example 3.) 21. f(2) = -2, f(1) = 1 22. f(5) = 7, f(-2) = 0 23. f(-4) = 2, f(6) = -3 24. f(-10) = 4, f(-2) = 4 5 25. f(-3) = 1,f(13) = 5 26. f(-9) = 10, f(-1) = -2 In Exercises 27-30, tell whether the data in the table can be modeled by a linear equation. Explain. If possible, write a linear equation that represents y ercept as a function of x. (See Example 4.) 27. X 2 4 6 8 10 5 15 29 47 28. X -3 - 1 1 3 5 V 16 10 4 - 2 8 29 30.
