Answer:
1
Step-by-step explanation:
Well slope intercept is y2-y1 over x2-x1
So,
-6-(-9) over 9-6
3 over 3 which is 1
Your slope is 1
 
        
                    
             
        
        
        
Solving:
1) Pass: Make the rule three (Directly proportional) 
Two inch nails ______ grams (<span>Weight)
</span>15 ----------------------------35
n ----------------------------- 175
2) Pass: <span>Multiply cross
</span>

3) Pass: Simplify




Answer:
75 nails weigh 175 grams
 
        
        
        
Step-by-step explanation:
B) perpendicular and intersecting
 
        
             
        
        
        
For this case, the first thing to do is find the area of the trapezoid.
 We have then: 

 Where,
 b1: b2: Trapezoid bases
 h: height of the trapezoid
 Substituting values we have: 

 Then, the cost per square foot is given by:
