What is the definition of infinite solutions?

• Slopes are the same, and the y-intercepts are the same. The lines are the same.

• The slopes are the same, the y-intercepts are different. The lines are parallel.

• The slopes are different. The lines intersect at one point.

Are the points on the boundary line part of the solution set or not?

• Yes, they are part of the solution set because a solid line means those points ARE included

• No, they are NOT part of the solution set because a solid line means those points ARE NOT included
