Write a linear function f with the given values.
f(x)=___

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
