Sol'n:
 The graph of the equation 2x + y = -3 is a straigth line.
the formula is;
y=mx+b
        where 'm' is the slope
                 'b' is the y intercept.
To graph of this equation you can also trial and error.Assign the vaue of either X or Y by Zero .Say,
 y=-2x-3     ------that is the equation above.Im just only into the form above.
Let:                                    Let:
Y=0                                         X=0
0=-2X-3                                    Y=2(0)-3
X=-3/2                                      Y=-3
(-3/2,0)                                      (0,-3)
Therefore the coordinates are:
(-3/2,0) & (0,-3)
Then, plot on the Cartesian plane.

Hope it helps.:)
