Question 1061290
For the given line:
{{{ -2y = 4 - x }}}
{{{   y = (1/2)x - 2 }}}   so slope is 1/2

Parallel line will have slope = 1/2:
{{{  y = (1/2)x + b }}}

This line passes through (1,-6)  (x=1, y=-6), use this to find 'b':
{{{ -6 = (1/2)(1) + b }}}
{{{   b = -(13/2) }}}
—
Equation of parallel line is:
{{{  y = (1/2)x - (13/2) }}}
————————

Perpendicular lines have slopes that are negative reciprocals:  so if m is the slope of one line, then -1/m is the slope of a line perpendicular to it.

{{{y = ((-1)/(1/2)) x + b }}}
{{{ y =  (-2)x + b }}}

Find b using the same technique as above (1,-6) ==> y=-6 when x=1:

Then solve for b then re-write the equation of the line in final form.
