9 squares = 18 triangles * * * * * The correct answer is 76. There are 9 points in the grid. You can pick any 3 out of these 9 points in 9*8*7/(3*2*1) = 84 ways. However, 3 will form horizontal lines in the grid, 3 will form vertical lines in the grid, and 2 will form diagonal lines in the grid. None of these 8 triplets will form triangles, but all the rest will. So the answer is 84-8=76.
The lines that pass through points 4 -6 2 -3 and 6 5 3 3 on a grid are the lines y=x.
This is a "grid."

Grid references are a way to precisely pinpoint a location on a map by using intersecting lines on a grid. The vertical lines are numbered and are called eastings, while the horizontal lines are lettered and are called northings. The intersection of a specific easting and northing provides a unique reference point on the grid to locate a particular place.

Books that have grid lines are called Graphing Books .
You do not add more grid lines, they are present for all displayed cells. But, you can turn the grid lines on or off. In Excel 2007, go to the Page Layout tab in the Sheet Options and turn the grid lines on or off by checking or unchecking the box in front of View (under Grid Lines).
