See below.

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.
