Hope this was helpful !
I'm not positive I know the answer, but I have a feeling that because it's asking that you select all that apply, there is more than just one answer.
x + 3 = 0
-3 + 3 = 0
So yeah, just basically solve them as individual problems. Just do additive inverse for each expression.
Step-by-step explanation:
X + 9= 7
get x by itself you -9 on both sides
X + 9 = 7
- 9. -9
X = -2
SINCE the slope is -2 it would be like this -2/1 but first plot the y-intercept onto the graph and go down 2 and over 1.
