Answer:
If you solve a linear equation you have two different lines.
Now with that being said the solutions are as follows;
<u>One Solution</u>: The slopes are different
<u>No solution</u>: The slopes are the same and the y intercepts are different
<u>Infinite Solutions</u>: The slopes are the same and the y intercepts are different
 
        
             
        
        
        
Answer:
y=-x-9
Step-by-step explanation:
y-y1=m(x-x1)
y-0=-1(x-(-9))
y=-1(x+9)
y=-x-9
 
        
                    
             
        
        
        
Answer: C) d+13/d+4
Here’s why:
Step 1: Rewrite the factor 
d^2 + 7d +4d +28 / (d+4)^2 + 6 / d+4
Step 2 : factor out d from the expression and factor out 4 from the expression
d × (d+7) + 4(d+7) / (d+4) ^2 + 6 / d+4
Step 3: Factor out d+7 from the expression 
(d+7) × (d+4) / (d+4) ^2 + 6 / d+4
Step 4: simply the expression 
d+7 / d+4 + 6/ d+4
Step 5: write all numerators above the common denominator 
d+7+6 / d+4
Step 6: add the numbers and you get 
d+13 / d+4
        
             
        
        
        
Try this option:
way 1: using the picture, if x=-3 then y=-6.
way 2: the equation of this line is y=x-3; it means that y(-3)=-6.
