Question

An inverse relationship can be represented by:
a straight line
a bar chart

Answer 1

The correvt answer its

xy=k

hope it helps

can i get the brainyest please???

Answer 2

An inverse relationship can neither be represented by a straight line nor by a bar chart. But it can be represented by "xy = k"

Step-by-step explanation:

Inverse relation is used for the values which are inversely related to each other. For example: Let suppose you have a value x and y. Then an increase in the value of x will result in the decrease of value y. Mathematically it is represented as,

x ∝ 1 / y

Where;

∝ = proportionality

Replacing the proportionality sign by a constant value "k" the relation becomes,

x = k / y

Solving for k,

x y = k

Conclusion:

Hence, an inverse relationship can be represented by "xy = k"
