Question

x | -1 | 0 | 1 | 2 | 3 |

y | 1 | 2 | 3 | 4 | 5 |

## The correct answer is:

### A given set of coordinates (x, y) is said to be the solution of a given linear equation if-

when the value of such x & y coordinates are substituted in the given equation, LHS = RHS.

Hence, we will substitute all the given points in the equations (options) given and check whether

LHS = RHS for all those points.

Step-by-step solution:-

In the adjacent table, we substitute the values of x & y in each equation and check whether LHS = RHS.

Final Answer:-

Since, the coordinates of all points given in the question satisfies the equation in Option A,

Option A i.e. y = x + 2 is the correct answer.

Note:-

During actual exam, there is no need to solve for all the 4 options. Once, Option A satisfies the condition given in the question, student can move forward to solve the next question to save time.
