Write an equation of a line parallel to line gh below in slope-intercept form that passes through the point (-5, 6).
y = _x _ 1
y = x _ 1
y = _x + 11
y = x + 11

There are several information's of immense importance already given in the question. Based on those information's. the answer can be easily deduced.

We already know that
y = mx + b
Then
Slope for GH = (6 - 2)/(- 2 - 2)
                      = - 1
We already know that parallel lines have the same slope
Then
6 = -1(5) +b 
6 = - 5 + b
b = 11
Then, the equation is 
y = x + 11
From the above deduction, it can be easily concluded that the correct option among all the options that are given in the question is the last option or the fourth option.
