Question

find one set of ordered pair which belongs to a straight line represented by an equation y=2x-1​

Answer 1

Answer:

ANSWER

Given Equation is

y=2x−1

Rearranging the equation

2x−y=1

From option A

LHS =2−1=1= RHS

Hence, (1,1) lies on the line y=2x−1

From option B

LHS =4−1=3= RHS

Hence, (2,1) is not a solution.

From option C

LHS =2−2=0= RHS

Hence, (1,2) is not a solution

From option D

LHS =6−1=5= RHS

Hence, y=2x−1 is not a solution.

Hence Option A is the right answer
