The line passing through the points (−1,8)(-1, 8)(−1,8) and (6,−4)(6, -4)(6,−4) crosses the x x\,x axis at point AAA, the y y\,y axis at point B B\,B and O O\,O is the origin.
Find an equation of the straight line passing through the points (−1,8)(-1, 8)(−1,8) and (6,−4)(6, -4)(6,−4). Give your answer in the form ax+by+c=0ax + by + c = 0ax+by+c=0, where aaa, b b\,b and c c\,c are integers.
