For the table of values, choose x = -4, -2, 0*, 2 and 4; calculate the y values that correspond.
* when you set x = 0, you get, of course, y = -3, which is the yintercept.
When you set y = 0, you see that (3/2)x = 3 so x = (2/3)(3); this gives x = 2 as the x intercept.
For graphing purposes, it is sufficient to use just the x and y intercepts(always true unless b=0).
To get the standard equation, multiply by 2 throughout, getting 2y = 3x - 6 and then finally 3x - 26 = 6.
