Step-by-step explanation:
16k / 7k
Divide the numbers
16/7
Divide the variables
k/k = 1
16/7
It depends on which type of graph you want, but here's one:
so first you might want some square paper, then draw axis (x and y). then you can put measurements on it.

and so on
Answer:
B. y = -0.58x^2 -0.43x +15.75
Step-by-step explanation:
The data has a shape roughly that of a parabola opening downward. So, you'll be looking for a 2nd-degree equation with a negative coefficient of x^2. There is only one of those, and its y-intercept (15.75) is in about the right place.
The second choice is appropriate.
_____
The other choices are ...
A. a parabola opening upward
C. an exponential function decaying toward zero on the right and tending toward infinity on the left
D. a line with negative slope (This might be a good linear regression model, but the 2nd-degree model is a better fit.)
