Answer:
Step-by-step explanation:
I don't know what your teacher thinks about solving this in terms of slope/ y intercept. I'll it that way. It makes things much easier to graph which I'll also include.
y - 2 = -1/2(x + 3) Remove the brackets.
y - 2 = -1/2x - 1.5 Add 2 to both sides.
y = -1/2x - 1.5 + 2
y = -1/2x + 1/2
You can make a small table if you like
x y
0 1/2
1 0
2 -1/2
You should check the last entry
y = -1/2 * 2 + 1/2
y = -1 + 1/2
y = -1/2
