Answer: [tex]y=-0.54x+19.8[/tex]
Step-by-step explanation:
Because it is asking for a line, it cannot be the first option (which is a quadratic) or the fourth option (which is an exponential).
This leaves us with the second and third options.
Since the line will have a negative slope (as the data is decreasing), this means that the only viable option is [tex]y=-0.54x+19.8[/tex].
