Answer:
(-2,3,10,8)
Step-by-step explanation:
 eg
(x,y)=(domain,range) 
x components are domain and y components are range in the given set of ordered pairs
 
        
             
        
        
        
Answer:
2 and - 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3y = 6x + 9 ( divide all terms by 3 )
y = 2x + 3 ← in slope- intercept form
with slope m = 2
(i)
Parallel lines have equal slopes, thus
the slope of line t is 2
(ii)
Given a line with slope m then the slope of a line perpendicular to it is
 = -
 = -  = -
 = -  , thus
, thus
the slope of line r is - 
 
        
             
        
        
        
Answer:
The total number of pencils is 6
Step-by-step explanation:
According to the given scenario, the computation of the total number of pencils is as follows:
There are 18 students 
And let us assume there is m mechanical pencils that put in each bag
also he put twice of the regular pencil
So if he put the 3 mechanical pencil 
So, the total number of pencils is 
= 3 × 2 
= 6
As it twice of the regular pencil
hence, the  total number of pencils is 6
 
        
             
        
        
        
The point-slope form:

We have:

Substitute:

Answer: C. y - 5 = 3(x + 1)
