- in a line like y=-5x+10 a solution is when one side is equal to the other.
in y = -5x + 10 you can substitute (0,10) for x and y
and your answer will be 10=10
- on a graph the solution is a one of many points that land on the line
- a system of equations means that x and y make both of the equations equal.
- a solution for two equations is where the lines intersect
- on a graph it means the exact point where the lines intersect
