<h3><u>
Answer:</u></h3>
Hence, the equation of line is:
y= -6x
<h3><u>
Step-by-step explanation:</u></h3>
Clearly from the graph we could see that the line passes through the point (0,0) and (-1/2,3).
Also we know that the equation of a line passing through (a,b) and (c,d) is given as:

Here we have:
(a,b)=(0,0) and (c,d)=(-1/2,3)
Hence, the equation of line is:

Hence, the equation of line is:
y= -6x
 
        
        
        
Answer:
x = 13
Step-by-step explanation:
call the missing number x
8 - x = - 5                        Subtract 8 from both sides
8-8 - x = -5-8                  Combine
-x = - 13                           Multiply by -1
x = 13
 
        
             
        
        
        
The given equation is

First we solve for y, and for that, we have to islolate y, that is

And it pass the vertical line test. So here y is a function of x .
So we can define the given equation as y as a function of x .
