Answer:
a) (1, -2)
Step-by-step explanation:
The given inequality is y < -|x|
We substitute the point to see which points satisfy the inequality.
For a) (1, -2), we substitute x=1 and y=-2 to get:
-2 < -|1|---------->-2<-1--------->True
For b) (1, -1), we substitute x=1 and y=-1 to get:
-1 < -|1|---------->-1<-1--------->False
For a) (1, 0), we substitute x=1 and y=0 to get:
0 < -|1|---------->0<-1--------->False
The first choice is correct.
-21a + 16a = -5a
5(x + 10) + x = 5x + 50 + x = 6x + 50

Step-by-step explanation:
Answer:
y=1/3x+6
Step-by-step explanation:
Equations parallel to each other have the same slope so that rules out the fourth answer. Perpendicular equations have opposite and reciprocal slopes, which in this case would be 
, which rules out all of the others except for the third option.
