Answer -
(i)x + y = 4
x = 4 – y
If y = 0, then x = 4
If y = 4, then x = 0
Now plot the points (4, 0) and (0, 4) on the graph and join them ro get the graph of the given equation
(ii)x – y = 2
x = 2 +y
If y = 0, then x = 2 and if y = 1,
Then x = 2 + 1 = 3
Now plot the points (2, 0) and (3, 1) on the graph and join them to get the graph of the equation.
(iii) -x+y = 6 ⇒ y = 6+x
If x = 0, then y = 6 + 0 = 6
If x = -1, then y = 6 – 1 = 5
Now plot the points (0, 6) and (-1, 5) on the graph and join them to get a graph of the line.
(iv) y = 2x
If x = 0, then y = 2 x 0 = 0
If x = 1, then y = 2 x 1 = 2
Now plot the points (0, 0) and (1, 2) on the graph and join them to get the graph of the line.
Now plot the points (5, 0) and (0, 3) on the graph and join them to get the graph of the line.
Now plot the points (4, 0) and (2, -3) on the graph and join them to get the graph of the line.
Now plot the points (-1, 2) and (2, 3) on the graph and join then to get the graph of the line.
Now plot the points (1, 0) and (-1, 1) on the graph and join then to get the graph of the line.
