Question 998804
Review how signed numbers work, meaning, their operations.
(-)(-)=(+);
(-)(+)=(-);
(+)(-)=(-);
(+)(+)=(+).
This is similar for division.


{{{-2y = -x-2}}}
Solve for y in terms of x.


{{{(-2y)(-1/2)=(-x-2)(-(1/2))}}}
Distributive Property on the right member, and multiplicative inverse very simply on the left member.
{{{highlight(y=x/2+1)}}}----should be well understood, and hopefully you can fill-in any steps
which you believe to be "missing".


That is now in slope-intercept form.
The y-intercept is  (0,1), and the slope is  {{{1/2}}}.
-
Start the graph at point  (0,1), and according to slope, move up 2 units and move rightward
by 1 unit; and keep going for whichever other points you want to find on the line.


{{{graph(300,300,-2,5,-2,5,x/2+1)}}}
