Answer:
a.1
b. 17
Step-by-step explanation:
So the | | around an equation makes it an absolute value which can be defined as the "distance from zero" or in other words, if a value is positive, it stays positive, and if a value is negative, it becomes positive.
|-8 + 9| = |1| = 1
|-8| + 9 = 8 + 9 = 17
Bar graphs sorry if I’m not right
From general equation of a line;
y=mx+c
m=
![\frac{change in y}{change in x}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bchange%20in%20y%7D%7Bchange%20in%20x%7D%20)
m=
![\frac{0--3}{-2-1}](https://tex.z-dn.net/?f=%20%5Cfrac%7B0--3%7D%7B-2-1%7D%20)
m=-1
y=-x+c
Finding value of c;
using point (-2,0)
0=-(-2)+c
c=-2
y=-x-2
