Question: j 3x - 7y - 42 = 0 k x = 3y -5 1 ly =- x+7 4 2x - 3y - 18 = 0

j 3x - 7y - 42 = 0 k x = 3y -5 1 ly =- x+7 4 2x - 3y - 18 = 0 2x - 3y = 21 3 -x - 4 5 The line y = 2x intersects the line y = x + 6 at the point A. Find the equation of the line that passes through A and has gradient 3. 6 The line y = 2x - 4 intersects the line y = -3x + 6 at the point B. Find the equation of the line that passes through B and is: a parallel to the x-axis b parallel to the y-axis 7 The line y = x intersects the line y = 2x + 1 at the point A, and intersects the line y = -3x + 12 at the point B. The line y = 2x + 1 meets the line y = -3x + 12 at the point C. Find the coordinates of the vertices of triangle ABC. 8 The line that passes through the points A(0, 2) and B(1, 4) meets the line that passes through the points C(1, 8) and D(-1, 10) at the point E. Find the equations of the lines AB and CD and hence find the coordinates of E
