Line L intersects the x-axis at point A and the y-axis at point B, as shown on the diagram. The length of line segment OB is three times the length of line segment OA, where O is the origin. Find the gradient (slope) of L. Point (2, 6) lies on L. Find the equation of L in the form y = mx + c. Find the x-coordinate of point A.

The points A and B have coordinates (4, 6) and (12, 2) respectively. The straight line l1 passes through the A and B. a. Write an equation for l1 in the form ax + by + c = 0, where a, b and c are integers. The straight line l2 passes through the origin and has gradient -4. b. Write down an equation for l2. The lines l1 and l2 intersect at the point C. c. Find the coordinates of C.
