Ordinate is one less than absissa
Generalize the pattern and plot all points with given property
If we let the abscissa be represented by the variable x, then the ordinate would be represented by x - 1.
Therefore, all points (x, y) with this property would have the coordinates (x, x - 1) where x is any real number.
Here are a few example points with this property:
(0, -1)
(1, 0)
(2, 1)
(3, 2)
To plot these points, simply draw a line passing through the points (0, -1), (1, 0), (2, 1), (3, 2), etc. This line would have a slope of 1 and would pass through the origin.
