Question

Determine, by drawing graphs, whether the following system of linear equations has a unique solution or not:

(ii)  2y=4x -6, 2x= y+3

Answer 1

Thus, we have the following table giving points on the line 2y =4x -6

Thus, we have the following table giving points on the line 2x = y+3

We find the graphs of the two equations are coincident,
Hence, the system of equations has infinity many solutions
