Since the only information given is that the order pair (1,4) is a solution of the system of linear, we are therefore having an infinite number of options. The trivial equations would be: x = 1 y = -4
We can write equations combining both variables as: y = 4x y = 3x + 1 y = 2x + 2 y = x + 3 y = -4x + 8 y = -3x + 7 y = -2x + 6 y = -x + 5
All the above can be used as linear equations of the line and would have (1,4) as a solution. In order to define the exact line, we need at least two points, which are not given in this question.
