Answer:
y - 2 = 6 (x - 1)
Step-by-step explanation:
Slope intercept form equations look like this: 
y - y1 = m (x - x1)
***m = 
Using the point (1,2), we know that x1 = 1 and y1 = 2. Let's sub these values into the slope intercept equation:
y - 2 = m (x - 1)
To complete this equation, we need to find slope. Pick out another point on the graph and plug into the slope equation. We can use point (2,8), where (1,2) = Point 1 and (2,8) = Point 2.
 
Now that we know m = 6, let's plug that back into the original equation to get our final answer:
<u>y - 2 = 6 (x - 1)  </u>          
I hope this helps!
 
        
             
        
        
        
1) 
The graph of the above equation is attached in the attachment below.  
For all the values from negative infinity to -4, the function is positive.  
X ∈ (-∞,-4]
2) 
To find the x- intercept, plug y =0  



x intercept = (2,0)
To find the y- intercept, plug x=0  


Y- intercept = ( 0,3)
3) 
Y- intercept = (0,13)
x- intercept = (13,0)

14/12 because if u go on calculator and do 5 divided by 12 + 9 divided by 12 u get 1.166667 or something and then u do 14/12 and it’s the same number.
