Question 955846
Determine whether they system of linear equations has one and only one solution, infinitely many solutions, or no solution. Find all solutions whenever they exist.
 2x – 5y = 10
 4x – 10y = 20
 -------
Notice that both equations have slope = 2/5
The lines are parallel.
Ans: No solutions because the lines do not cross at any point.
