Do All Graphs Have Points with Integral Coordinates?
The development of the general equation of a line (ax + by = c) is usually based on geometric intuition and the concept of slope. Students are given a point, (a, b), whose coordinates are integers, and a slope, m, and asked to write the equation of the line and graph it.
