Some of the solution sets of two linear equations in two variables are the following ordered pairs { (0, - 1), (1.1),(3,5), (5,9) and { (0,3), (1.1), (4,-5), (6,9) }. What can you conclude? a. the graph of the two lines start at (1,1). b. the graph of the two lines are perpendicular at (1,1). c. the graph of two lines are parallel to the point (1,1). d. the graph of the two lines intersect at (1,1).
