Answer:
x−2y=3
When x=0,y=−23
y=0,x=3
(i) When x=5,5−2y=3
⇒2y=2
⇒y=1
∴ The coordinate is (5,1).
(ii) When y=0,x−0=3
⇒x=3
∴ Coordinate is (3,0).

Answer:
Given that, x-2y=3
when x is 9 [as per (i)]
9-2y=3
→-2y=3-9
→y=-6/-2
→y=3
Then, when x is 9, y will be 3.
Now when y is 5 [as per (ii)]
x-2×5=3
→x=3+10
→x=13
Then, when y is 5, x will be 13.
From the above we get two coordinates,
(9,3) and (13,5).
The graph will be constructed by these two points as it's in the attachment.
Hope it helps you...
