.....you have here a linear equation and the graph will be a line..to graph a line you need two points that lie on a line because a line is defined by two points
your equation is also written in

form

where

is a

and

is
so, here

is

and that is one point; (0,-4)
now you can find second point: if you take

you will find

.....so, the second point is
now you can plot a line:
