in y = mx + b form, the m stands for the slope and the b stands for the y int.
y = 6x + 9....slope = 6, and y int = 9
y = 6x + 2...slope = 6, and y int = 2
when ur equations have the same slope but different y intercepts, they are parallel lines with no solution.
* if they would have had the same slope and the same y int, they would have had infinite solutions.
* if they would have had different slopes and different y intercepts, they would have had 1 solution
