# Lattice Point and Distance Formula

I need help understanding the following problem set.

1. Mark a point at the intersection of two rulings. The lattice point. Seven units to the right and four units up, mark another. Use a ruler to find the distance from one point to the other, using the distance between two parallel rulings as the unit. What degree of accurancy can be guaranteed?

2. Mark a lattice point. Four untis ot the left and seven units down, mark another. Use a ruler to find the distance form one point to the other.

3. What is the distance from point (4,2) to the point (-3,-2)? Explain the method used.
