Answer:
The y-intercept is the point (0,-8)
see the attached figure
Step-by-step explanation:
we have

we know that
The y-intercept is the value of the function f(x) when the value of x is equal to zero
so
For x=0

therefore
The y-intercept is the point (0,-8)
see the attached figure to better understand the problem
 
        
             
        
        
        
In one year there are 365 days of 24 hours. Each hour has 60 minutes and each minute is 60 seconds long. So, 60s/min x 60 min/hr x 24hr/day x 365 days equals 31,536,000s. 
Hope this helps you with your answer. If it is incorrect, then I am sorry.
 
        
                    
             
        
        
        
Slope = 2/3 (positive 2/3)
You use the formula Y2-Y1/X2-X1 in order to get the slope
 
        
        
        
Answer:
 d= bv + r
Treat it like you would a normal equation. Multiply by b and add r to isolate d.
