Answer:
<h2>Option D is the right answer.</h2>
Step-by-step explanation:
We need to find the option for which the value of the function will be increasing, with the increasing variable.
Vertical line means the value of the x is constant, for any y. Hence, it is not the answer.
Horizontal line represents constant functions. Hence option B can not be the answer.
The data having a positive slope represents a <u>increasing function with the increasing variable</u>. Vice-versa for the data having a negative slope.
That is why option D will be the answer.
