Using the points (4,2) and (9,6) find each of the following:
(a) The slope of the line passing through both points.
(b) The equation of the line passing through both points in point-slope form.
(c) The equation of the line passing through both points in slope-intercept form.
(d) The equation of the parallel line that passes through the point (0,11)
(e) The equation of the perpendicular line that passes through the point (3,6).
