Answer:
Step-by-step explanation:
solve each inequality:
A : x+6<8  ,  x<-8-6 , x<-14
B: x+4≥-6 ,  x≥-10
C: x-3>-10 , x>-7
D:x≤-9
since -12 is on the left side of the number line then x≤ -9 would be the solution

Answer:
the x-axis is the middle horizontal line
the y-axis in the middle vertical line
the origin is (0,0) or where the x and y-axis cross
in the upper left quadrant the x-axis is negative and the y-axis is positive.
in the upper right quadrant the x-axis is positive and so is the y.
in the lower left quadrant both the x and y-axis is negative.
in the lower right quadrant the x-axis is positive and the y-axis is negative.
