This exercise emphasizes the "mechanical aspects" of working with linear equations. Find the equation of a line with the following characteristics. (a) Passing through the points (1, -1) and (-2, 4) (b) Passing through the point (-1 -2) with slope m = 30. (c) With y-intercept b = -7 and slope m = -6. (d) Passing through the point (6, 11) and having slope m = 0. (e) Perpendicular to the line in (a) and passing through (1, 1). (f) Parallel to the line in (b) and having y-intercept b = -15. (g) In slope intercept form having the equation 3x + 5y = 4. (h) Crossing the x-axis at x = 2 and having slope m = 1.
