Question
| x | -1 | 0 | 1 | 2 | 3 |
| y | 1 | 2 | 3 | 4 | 5 |
and their corresponding values of y. Which of the following equations shows a possible relationship between x and y ? 
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.
