The intersection point of two lines on the graph indicates that the solution of two linear equations is undefined.
S1 : The graph of a linear equation is a straight line
S2 : The solution of a pair of linear equations is a point common to two lines.
A unique solution for a pair of linear equations is obtained if
S1 : the graphs of the equations have only one point of intersection.
S2 : The ratio of coefficients of the two variables is equal.
If the equations in a system of two linear equations in two variables are graphed, each graph will be a line. Which of the following System of Linear equations will have only one solution ?
