Hello!
Usually in a slope intercept equation, the y-intercept is a term, and is not a coefficient of x. The slope is usually multiplied by x. This eliminates A and C as answers.
Usually the y-intercept is a starting point. Not the slope. This means that B is also incorrect.
In D, it has the correct y-intercept. It shows that 16 dogs visited the first day, and the slope shows a constant rate of more dogs.
Therefore, our answer is D.
I hope this helps!
