See below

Choose values for $x$ $x$ and compute $y$ $y$ to come up with a bunch of ordered pairs to plot.

It's good practice to choose a few negative values, zero and a few positive values:

(3,3.5)
(2,1)
(1,-0.5)
(0,-2)
(-1,-3.5)
(-2,-5)
(-3,-6.5

You could change the equation to slope-intercept form:

$y = m x + b$ $y=mx+b$

$- 2 y = 4 - 3 x$ $-2y=4-3x$

y=3/2x-2

This tells us that the slope is $\frac{3}{2}$ $3/2$ and the y-intercept is $- 2$ $-2$ which checks with the above ordered pair.

graph{3/2x-2 [-10, 10, -5, 5]}

How do you graph 3x - 2y =43x−2y=43x - 2y =4 by plotting points?
