Question

draw the graph of 2x+y=9​

Answer 1

Answer:

2x-y-1=0

=>2x=y+1

=>x=___y+1____

2

This table for 2x+y-1=0 is

X 2 1 0

Y 3 1 -1

Also we have

2x+y=9

=>2x=9-y

=>x= 9-y

__________

2

The table for 2x+y=9 is

X 2 1 0

Y 3 1 -1

Also we have

2x+y=9

=>2x=9-y

=>x= 9-y

__________

2

The table for 2x+y=9 is

X 4 3 5

Y 1 3 -1

Plotting the Above Points We Get the following required graph.

From the above graph it is clear that two lines 2x-y-1=0 and 2x+y=9 intersect at the point(2,5,4).

Do in the graph book.
