Graph the line
and then find the points on the graph that intersect the integer grid. You'll the only two points that fall on integers grid is (9,0) and (4,2)
4x + 6y=125 can;t happen since no combination of even numbers can add to an odd result
5x+10y must end in either 5 or 0. No way to get to 112
1)Graph and see if there are points on the grid (assumes grid is on integers)
2)Plug and try (100,91,82,73,64,55,46,37,28,19,10,1) Any any of those evenly divisible by 6? I dont think so
