Full solution stays hidden until you ask for it.
1. A graph of an equation shows all coordinate pairs that make the equation true.
2. Therefore any point on the graph satisfies the equation.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Saying only that the point is 'on the line' without connecting to the equation.
