One set of ordered pair which belongs to a straight line represented by an equation Y = 2 x- 1

Open in App

Solution

The solution can be found out only by trial and error method
put (0,0) ie x=0,y=0
We get 0=-1
Hence condition is not satisfied.
Now try (1,1)
We get 1=2×1-1
1=1
Which is true
Hence one set of ordered pair which belongs to the line y=2x-1 is (1,1)
