Answer:
The correct option to tell whether a relationship is proportional or not is;
Step-by-step explanation:
A proportional relationship is a relationship between two variables, 'x', and 'y' such that they have equivalent ratio, such that all values of variable 'y' are given by the product of the values of the variable 'x' and a constant, 'k'
Therefore, y = k · x, from which we have;
Therefore we can use to tell whether a relationship is proportional or not proportional.
Answer: ( 2 , - 15 )
Step-by-step explanation:
Given :
endpoint = ( 0 , -1 )
midpoint = ( 1 , - 8 )
Let the other end point be ( x , y )
The equation for finding the mid point of a line segment is given by :
mid point = ( ,
This means
(1 , -8 ) = ( ,
)
Equating the x - component , we have
1 =
1 = x/2
Therefore
x = 2
Also equating the y - component
- 8 =
-16 = -1 + y
-15 = y
Therefore :
y = -15
Therefore , the other endpoint is :
( 2 , - 15 )
