Question 1171477: Could you verify if I have corrected determined the correct type of linear equation graph along with the common solution coordinates of the graph (which I cannot attach)to below problems?
Graph and label these systems of linear equations. State whether they are consistent, inconsistent or dependent. If they are consistent, give the common solutions of where they intersect on graph.
Problem 1:
x-y= 4
5x-3y= 8
After working and plotting this graph it is: Consistent graph with solution of -2, -6
Problem 2:
2x-y= 2
3x-y= 18
After working and plotting this graph it is: Consistent graph with solution of: 4, 6
Problem 3:
x+3y= 9
2x+6y= 14
After working and plotting this graph it is: Inconsistent graph with no intersection (2 parallel lines plotted side by side on graph).
Thank you
