in helmholtz vector equation why F=-∆ф+∆xA?
Not enough information has been given because in order to work out a straight line equation the slope and coordinates of (x, y) must be given
Subtract the equation of one line from the equation of the other
By substitution
You need a pair of coordinates to work out the slope-intercept equation.

-4x + 9y = 0 is the equation of a line in the Cartesian plane and the coordinates of any of the infinite number of points on that line will satisfy the equation.
The coordinates of every point on the graph, and no other points, are solutions of the equation.
The solution set for a given equation is the set of all points such that their coordinates satisfy the equation.
