The system of equations n=m and n=4m is the point (0,0). which of the following statements is true. a. (0,0) is a solution to n=m and to n=4m. b.no point no the line n=m is also on the line n=4m. c.every solution to n=m is also a solution to n=4m. d.the graph of the solution is parallel lines.

A. (0,0) is a solution to n=m and to n=4m.

The equations can be solved by any of the usual means. Using substitution, we have ...

... m = n = 4m

... m(4 -1) = 0 . . . . subtract the left side

... m = 0 . . . . . . . . divide by 3

... n = m = 0

The solution is (m, n) = (0, 0).
