Question

Match the following expressions with their correct values of $x$ and $y$:

• A. (1,4)
• B. (2,5)
• C. (7,10)
• D. (5,9)

Answer 1

Let us consider: $y=2x+1$
For $x=2$, we get y as $y=2\times 2+1=4+1=5$
∴ (2,5) satisifes the relation: $y=2x+1$

Now, consider $y=9x-5$
For $x=1$, we get y as $y=9\times 1-5=9-5=4$
∴ (1,4) satisifes the relationship $y=9x-5$


Now, consider $y=3x-11$
For $x=7$, we get y as $y=3\times 7-11=21-11=10$
∴ (7,10) satisifes the relationship $y=3x-11$


Now, consider $y=x+4$
For $x=5$, we get y as $y=5+4=9$
∴ (5,9) satisifes the relationship $y=x+4$
