GRAPHING REQUIRES 2 POINTS OR A POINT & A SLOPE VALUE.
SETTIONG X=0 GETS 1 POINT
Y=-1/2*0+3
Y=3 SO WE HAVE THE POINT (0,3)
NOW SET Y=O
0=-1/2X+3
-1/2X=-3 CROSS MULTIPLY
-X=-6
X=6 SO WE HAVE A SECOND POINT (0,-6)
LOCATING THES 2 POINTS & DRAWING A LINE THROUGH THEM GIVE YOU THE DESIRED LINE.

Solved by pluggable solver: PLOT a graph of a function
Plotting a graph:
graph%28+600%2C+400%2C+-10%2C+10%2C+-10%2C+20%2C+%28-1%2F2%29x%2B3+%29
This solver uses formula rendering system and here's the actual formula that was plotted:

graph( 600, 400, -10, 10, -10, 20, (-1/2)x+3 )
