Answer:
Option 1: y=-0.5x+14
Step-by-step explanation:
You can see that the third part of the graph is a downward slope, meaning it is negative, so eliminate option 2 and 4.
Let's find the slope with two points seen: (20, 4) and (12, 8)
[tex]\frac{y_2-y_1}{x_2-x_1} =\frac{4-8}{20-12}=\frac{-4}{8}=-\frac{1}{2} =-0.5[/tex]
So, the only option that abides by these requirements is option 1.
