Answer: f(x)= -2x+1

Step-by-step explanation:

Take any two points

I'll choose (1,-1) and (0,1)

Find slope:

[tex]\frac{1-(-1)}{0-1} =\frac{2}{-1} =-2[/tex]

Plug into linear equation:

y= -2x+b

Find b using a point as well:

I'll choose (0,1)

1= -2(0)+b

1=0+b

b=1

Final equation: f(x)=-2x+1
