WebDec 8, 2024 · Any line can be represented as, ax + by = c. Let the two points satisfy the given line. So, we have, ax 1 + by 1 = c. ax 2 + by 2 = c. We can set the following values so that all the equations hold true, a = y 2 - y 1 b = x 1 - x 2 c = ax 1 + by 1. These can be derived by first getting the slope directly and then finding the intercept of the line.
