Draw the graph of linear equation 5y = 3x + 18 on the Cartesian plane. From the graph check whether (-2,4) is the solution of linear equation or not.

We have,       5y=3x+18  y=35x+185When  x=0, we have:  y= 0+185=3.6When x=5, we have:  y= 3+185=6.6Thus, we have the following table giving points on the line  5y=3x+18




Plotting points A(0,3.6) and B(5,6.6) on the graph paper and join them, we obtain the graph of the straight line 5y=3x+18 as shown in figure.




From the graph, it is clear that (-2,4) is not the solution of linear equation.
