## Graphical solutions of solving equations

Two straight lines y=mx+c and y=nx+d are displayed.
The x coordinate of the point at which the lines intersect (indicated by the green arrow) will be the solution to the equation: mx+c = nx+d
Move points B and C. When do the fruits change?
How many solutions can such equations have? At most? At least?
