A lattice point is a point whose coordinates are integers. How many lattice points are strictly inside the triangle formed by the points (0,0), (0,7), and (8,0)?

Hello Guest!

 

\(f(x)=-\frac{7}{8}x+7\)

 

lattice points: 8+7+6+5+4+3+2+1+1

 

There are 37 lattice points in the triangle.

I suspect "strictly inside" excludes those on the boundary.
