Answer:
y=4x+2
Step-by-step explanation:
To find the slope of a line, you would do y₂-y₁/x₂x₁
This would be 2-6/0-1...
So your answer would be -4/-1 
After simplifying, your slope is 4.
To write this in slope-intercept form, that would be y=4x+2
 
        
             
        
        
        
Answer:
The GDP gap is 9 % when there is 4.5 % unemployment.
Step-by-step explanation:
The statement shows a reverse relationship, where an increase in unemployment is following by decrease in potential GDP and can be translated into the following rate:

The GDP gap at a given increase in unemployment can be estimated by the following expression:


Where:
 - GDP gap-unemployment increase rate, dimensionless.
 - GDP gap-unemployment increase rate, dimensionless. 
 - Increase in unemployment rate, measured in percentage.
 - Increase in unemployment rate, measured in percentage.
 - GDP gap, measured in percentage.
 - GDP gap, measured in percentage.
If  and
 and  , the GDP gap is:
, the GDP gap is:


The GDP gap is 9 % when there is 4.5 % unemployment.
