Answer:
-4
Step-by-step explanation:
Remember that the slope is given by
m = (y2-y1)/(x2-x1)
    
Using the points (-3,10) and (0,-2)
   = (-2-10)/(0--3)
   =(-2-10)/(0+3)
   -12/3
   -4
 
        
                    
             
        
        
        
Answer: X< -9
Step-by-step explanation: 7+2x<-11 move the constant to the right and change its sign. 2x<-11-7. Now calculate the difference, which should get to... 2x<-18. Then you just divide both sides of the inequality by 2. Which should get your answer.... X< -9
 
        
             
        
        
        
Any relation is x and y is said to be a Direct variation if one is a constant multiplier of the other .In other words we can say : when one variable changes the other changes in proportion to the first.
The Direct variation equation are of the type y=k.x
Here k is known as constant of proportionality .It has a fixed value.
The given equation is y=
If we compare this equation with y=k.x 
Then k=
