Select the ordered pairs that are solutions to the inequality two x minus three y greater than or equal to twelve

The rows and columns of lattice points in a three-by-three square array are evenly spaced one unit apart. how many distinct triangles with at least one side of length 2 units can be drawn using three lattice points for the vertices?

Ihonestly have no clue if it's each or none.

Determine if the equation defines y as a function of x: 2xy = 1. yes o no
