Answer:
7(-1/2 +2) = -6(2(-1/2) -1) +3(-1/2)
7(3/2) = -6(-2) -3/2
21/2 = 12 -3/2 . . . . . true, answer checks OK

Answer:
The direct variation equation can be given as:

Step-by-step explanation:
Given:
At a summer camp there are 6 campers under one counselor.
To find the direct variation equation for the number of campers in terms of number of counselor.
Solution:
Number of campers
Number of counselors
We have
∝ 
The direct variation equation can be written as:

where
is the direct variation constant.
There are 6 campers under one counselor. Using this statement we can find value of 
Given: when
then 
We have,

∴
Thus, the direct variation equation can be given as:

We can find the points using the equation to plot.
