Question

Draw the graph for 2x+y=6 and 2x-y+2=0. Shade the region bounded by these lines
Question of ncert book class 9th mathematics ​

Answer 1

Answer:

1. 2x+y=6
2. 2x-y+2=0

2x-y=-2

2x+y=6

sum Karne par

4x=4

x=1

x ka man smi mein rakhane par

2x+y=6

2×1+y=6

y=6-2

y=4

Answer 2

Answer:

2x+y=6

putx=0

y=6

putx=1

y=4

putx=2

y=2

and2x−y+2=0

puty=0

x=1

putx=0

y=2

putx=2

y=6

andx−y=0

x=0,y=0

x=1,y=1

x=2,y=2
