Step-by-step explanation:
(m - 2)x + y = 2
y = -(m - 2)x + 2
8 = -(m - 2)(2) + 2
6 = -(m - 2)(2)
3 = -(m - 2)
-3 = m - 2
-1 = m
mx + 2y = k
2y = -mx + k

The solutions for
is option 3. 
Step-by-step explanation:
Step 1:
First, we must bring the equation to the form of 
So
becomes 
The value of a is the coefficient of the
term, the value of b is the coefficient of x term and c is the coefficient of the constant term.
Comparing the above equation to
we get
and 
We have the formula 
Step 2:
By substituting the known values, we get


This is the third option.
