So to solve this question, your goal is to find out how the way it is solved is not correct. 
Your answer would be: On the third line, the student adds the 8 to both sides instead of subtracting. The way the initial equation is given is 
y-(-8)=-6(x-2). After distributing the six, the student should make the 8 positive because subtracting a negative makes a positive. After solving, the equation should look like: y(+8)=-6x+12, so you would subtract the 8 from both sides instead of adding it, and solve from there. 
 
        
             
        
        
        
Answer:

Step-by-step explanation:
The shortest distance d, of a point (a, b, c) from a plane mx + ny + tz = r is given by:
 --------------------(i)
                   --------------------(i)
From the question,
the point is (5, 0, -6)
the plane is x + y + z = 6
Therefore,
a = 5
b = 0
c = -6
m = 1
n = 1
t = 1
r = 6
Substitute these values into equation (i) as follows;




Therefore, the shortest distance from the point to the plane is

Answer:
1.5 bars of granola per student
Step-by-step explanation:
Number of students = 4
Number of granola bars = 6
Four students share 6 granola bars equally.
Each student gets = 6 ÷ 4
= 1 1/2
= 1.5 bars of granola per student
Each student's share is 1.5 granola bars.
