  Represent the following system of linear equations graphically 3 x + y ? 5 = 0, 2 x - y - 5 = 0  From the graph, find the points where the lines intersect Y-axis.

Answer:

                                 Given,                               ...(i) and                                  ?(ii) From Eq. (i), we get

x	0	1	2
y = 2 x - 5	5	2	-1

From Eq. (ii), we get

x	0	1	2
y = 2 x - 5	-5	-3	-1

Eqs. (i) and (ii) can be represented graphically as follows                              Here,  cuts Y-axis at (0,5) and                                                                     (1/2)      cuts Y-axis at (0,-5).            (1 /2)
