Answer:
2
Step-by-step explanation:
The given equation of line is
 
We need to find the slope of a line which is perpendicular to the given line.
The given equation can be rewritten as
 ...(i)
      ...(i)
If a line is defined as  , then the slope of the line is
, then the slope of the line is  
 
In equation (i), a=3, b=6 and c=18. So, slope of the line is
 
Let  be the slope of perpendicular line.
 be the slope of perpendicular line.
We know that product of two perpendicular line is -1.
 
 
Multiply both sides by -2.
 
Therefore, the slope of perpendicular line is 2.

The answer to this question is the school is going to have to rent 2 vans extra. The reason is because each van hols 8 people right. for the 6 vans that the school already owns, that will be 48 students in vans. When you subract that from 59, you get 11 students that still need a van, so 11 students can not fit in one extra van so the school would need two. Hope this gives you what you were looking for. God bless, and hope this helped. Also, please let me know if it was correct. 
 
        
             
        
        
        
System of equations:
We'll need one equation for the amount of pizzas, and another for the total cost of the pizzas. In this case, x will represent small pizzas, and y will represent large pizzas.
3x + 4y = 100
x + y = 30
Solving the system of equations:
First, we need to solve for one variable in one equation.
x + y = 30
x = 30 - y
Then, we'll take our equation that is solved for x and plug it into the other equation from above.
3(30 - y) + 4y = 100
Next, we solve for y.
90 - 3y + 4y = 100
90 + y = 100
y = 10
Finally, we take our value for y and plug it back in to the very first equation and solve for x.
x = 30 - 10
x = 20
Answer:
The student has sold 10 large pizzas and 20 small pizzas. 
Hope this helps!! :)
