Week 17 in math 10

The question asks us to find whether the system has no solution, one solution, or infinitely many solutions. First, we have to rearrange the equations given to slope y-intercept form (y=mx+b). That way, we can find out the slope and y-intercept of two equations. If they have same slope and different y-intercept, they are parallel and have no solution. However, if they have same slope and y-intercept, they are going to be infinitely many solutions. This case, we have different slope and y- intercept, which means two lines will join at some point for once and have one solution.
