(b) (2x+ y = 2) intersect x-axis at
(i) (0, 1)
(ii) (1,0) (iii) (0,0) (iv) (1,1)
(c) (2y = x = 4) intersect y - axis at
(1) (2,0)
(ii) (0, 2) (iii) (2,2) (iv) (0,0)
(d) From graph we observe, the given pair of linear equations represents
(i) unique solution
(ii) no solution
(iii) infinite solutions
(iv) none of these
(e) The system of given pair of linear equations are
(i) consistent (ii) inconsistent (iii) coincident
(iv)parallel
