Question -
Answer -
Solution:
Given linear equationsare
y = x …(i)
3y = x …(ii)
and x + y = 8 …(iii)
Table for line y = x,
Table for line x = 3y,
Table for line x + y =8
Plotting the points A(1, 1), B(2,2), C (3, 1), D (6, 2), we get the straight lines AB and CD.
Similarly, plottingthe point P (0, 8), Q(4, 4) and R(8, 0), we get the straight line PQR.
AB and CD intersectsthe line PR on Q and D, respectively.
So, △OQD is formed by these lines. Hence, thevertices of the △OQD formed by thegiven lines are O(0, 0), Q(4, 4) and D(6,2).
