Question

a system of equations has 1 solution. if 4x – y = 5 is one of the equations, which could be the other equation?

Answer 1

System of equations having only one set of solution are lines when graphed intersects at one point. The equations of the lines have different slopes and y-intercepts. It will have the opposite sign for the slope. One possible equation that will have 1 solution for the given equation,
4x -y = 5
is,
-4x -y = 5
