If x >= 0 and y >= 0, how many lattice points does the line y = -2x + 28 pass through? (A lattice point is a point with integer coordinates.)

See  the  graph   here  :    https://www.desmos.com/calculator/xkyg3ldml5

 

The  graph will pass through  2  lattice  points  every  time  x  changes  by  1

 

So....it will pass trough    2(14)  +  1   =   29 lattice points
