Question
Write the way to find k.
- y = kx
- x ⋅ y
Hint:
The constant of proportionality is the ratio of two proportional values at a constant value.
The correct answer is:
Here, we have to select the way to find k.
As we know, To check the constant of proportionality,we use y= k x where k is the constant ratio of y to corresponding x .
Hence, the correct option is (d).
To find the constant of proportionality, first identify the x and y variables. To find the ratio of weight to number of sticks, x will be the weight and y will be the number of sticks of butter. Use the equation k = y ÷ x to find the constant of proportionality.

The coordinates for the origin in the coordinate plane are________?
Since the origin is a reference point it will always be (0, 0). At any point which is represented as (a, 0) where ‘a’ arbitrary is any number will lie on the x-axis but not on the y-axis. Similarly, any point (0, b) where b is an arbitrary number will lie on the y-axis but not the x-axis. Also, any point (a, b) where a is an arbitrary number, as well as b, is an arbitrary number will not lie on the x-axis as well as the y-axis. Hence the intersection of the axis will have to be (0, 0).
