Question

The relation between the number of hours(x) spent and the number of pages written(y) is shown in the table. Which of the following shows the relation represented in the table?

• A. y = x +1
• B. y = x + 10
• C. x = y + 10
• D. y = x + 9

Answer 1

The correct option is B y = x + 10

From the given table, we observe that,

when x = 1, we get y = 11

when x = 2, we get y = 12

$⟹$ y = 2 + 10 = x + 10

when x = 3, we get y = 13

$⟹$ y = 3 + 10 = x +10

Hence, y is the sum of x and 10.

Hence, the required equation is y = x +10
