Answer:

See below.

Explanation:

Rearrange the equation into the form #y = mx + c#

where #m# is the gradient and #c# is the #y# axis intercept.

From example:
#4x - 2y = ( -1 )#

Subtracting #4x# from both sides:

#-2y = -4x - 1#

Dividing by #-2#

#y = 2x +1/2#

#y# axis intercept has coordinates #( 0 , 1/2 )#

Plug a value for #x# into equation to generate a value for #y#

Example: #x = 4 # then #y = 17/2#

Coordinates for new point #( 4 , 17/2 )#

Then draw a line between these two points.
