Answer :
i) To draw the graph, we need atleast two solutions of the equation.
x | 0 | 4 |
y | 4 | 0 |
(x, y) | (0, 4) | (4, 0) |
Thus, we draw the graph by plotting the two points from table and then joining by a line.

ii) To draw the graph, we need atleast two solutions of the equation.
x | 0 | 2 |
y | -2 | 0 |
(x, y) | (0, -2) | (2, 0) |
Thus, we draw the graph by plotting the two points from table and then joining by a line.

iii)To draw the graph, we need atleast two solutions of the equation.
x | 0 | 1 | -1 |
y | 0 | 3 | -3 |
(x, y) | (0, -2) | (2, 0) | (-1, -3) |
Thus, we draw the graph by plotting the two points from table and then joining by a line.

iv)To draw the graph, we need atleast two solutions of the equation.
x | 0 | 1 | -1 |
y | 3 | 1 | 5 |
(x, y) | (0, 3) | (1, 1) | (-1, 5) |
Thus, we draw the graph by plotting the two points from table and then joining by a line.
