Step-by-step explanation:

Start by making a table of (x,y) pairs that satisfy this equation. Notice that two pairs would be enough, but it is always safer to obtain at least three to see them actually "aligned".

We are trying to find values for y when x= 0, 2, and 4 to make our calculations simple:

$y=\frac{1}{2} x-3$

When x = 0 then: $y=\frac{1}{2} (0)-3=-3$ So we plot the value (0,-3) on the x-y plane.

When x = 2 then: $y=\frac{1}{2} (2)-3=1-3=-2$ So we plot the value (2,-2) on the x-y plane.

When x = 0 then: $y=\frac{1}{2} (4)-3=2-3=-1$ So we plot the value (4,-1) on the x-y plane.
