Write the equation for the line given the information below. Leave your answer in point-slope form (when possible). y - yı = m(x - x1)
38. slope = - containing the point (2,3).
39. containing the points (1, -3) and (-5,2).
40. slope = 0 and containing the point (4,3).
41. perpendicular to the line in #38 and containing the point (3, 4).
42. passing through the point (-4,2) with an undefined slope.
43. passing through the point (2,8) and parallel to the line y = 5/6x - 1.
