(7x)-6=-12           7 times a number is 7x or 7 times any variable. Six less than that is subtracting by 6 then it all equals -12
        
             
        
        
        
Answer:
y = 4x + -9
Step-by-step explanation:
The y intercept which is -9, is the point in which the graph crosses the x-axis
In order to find the slope we need to identify two clear points on the graph.
- (0, -9)
- ( 1, -5)
Now that we have our two points we need to find the distance between them.
As you can see on the attachment the distance between the two points is 4 units up and 1 unit to the right, therefore the slope is 4/1 = 4.
Final Answer: y = 4x + -9
 
        
             
        
        
        

 is equal to 2x, since it is the derivative of
