A triangle on a coordinate plane is translated according to the rule 18. 4(x, y). Which is another way to write this rule?
(x, y) - (x + 4, y - 8)
(x, y) - (x - 4y - 8)
(x, y) - (X-8, y + 4)
(x, y) (x + 8. y - 4)

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?
