Find an equation of the straight line passing through the points (−2,5)(-2, 5)(−2,5) and (5,−1)(5, -1)(5,−1). 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.
The line 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 the area of triangle AOBAOBAOB.
