10. Write each equation in slope-intercept form. y + 3 = - 3(x - 6). See Example 1.

24. Find the equation of the line that goes through the given point and has the given slope. Write the answer in slope-intercept form. (-1, - 5), - 8. See Example 1.

56. Find the equation of each line. Write each answer in slope intercept form. See Examples 3 and 4.
The line is parallel to -3x + 2y = 9 and contains the point (-2, 1).

62. Find the equation of each line in the form y = mx + b if possible.
The line through (3, 2) with undefined slope

e. Section 3.5: Exercises 6, 8, 18, and 26

6. Write a formula that expresses the relationship described by each statement. Use k for the constant in each case. m varies directly as p. See Example 1.

8. u varies inversely as n. (see 6)

18. Find the variation constant, and write a formula that expresses the indicated variation. See Example 2. c varies inversely as d, and c = 5 when d = 2.

26. Solve each variation problem. See Examples 3รข?"5. n varies directly as q, and n = 39 when q = 3. Find n when q = 8.
