A triangle has vertices (1, 1), (3, 7) and (5, 4). What is the distance between the centroid and the line 2x = -y - 2? Hint: The coordinate of the centroid can be obtained from the average of the x and y-coordinates of the vertices. 2. Find the equation of a line passing through (4, -5) when the intercepts are numerically equal but of opposite signs. 3. Find the point (x,4) which is 5 units from the line 12x + 5y - 6 = 0
