First you need to find the slope of the line:

m=6-(-2) / (-1)-0 =-8
equation of line is:
y=mx+b
y=-8x+6
for absolute value function:
if x<0
y=-8x+6
if x>0
y=+8x-6
Slope is -1/2
2-4/6-2=
-1/2
m=-1/2
Answer:
10x^7-5x^6+15x^3
Step-by-step explanation:
Distribute the 5x^3 to all the terms
The 3 angles need to equal 180
The middle angle is given as 100.
180 -100 = 80
There is an x on each side so you have 2x
2x = 80
X = 80/2
X = 40 degrees
