SOLUTION: Suppose you are solving a system of equations where one equation is y=|x| and the graph of the other equation is a line. What are the possible number of solutions? Select all that
Question 506810: Suppose you are solving a system of equations where one equation is y=|x| and the graph of the other equation is a line. What are the possible number of solutions? Select all that apply. Answer by Edwin McCravy(20055) (Show Source):
Here is the graph of y = |x| in green
Here is a line (in red) that does not intersect it at all.
So it is possible to have 0 solutions.
------------------------------------------
Here is a line that intersects it exactly 1 time:
So it's possible to have exactly 1 solution.
-----------------------------------------
Here is a line that intersects it exactly 2 times:
So it's possible to have exactly 2 solutions.
-----------------------------------------
Here is a line that coincides with the entire right side of
the graph:
So it's possible to have an infinite number of solutions.
------------------------------------------
So there can be 0, 1, 2 or an infinite number of solutions.
