The slope of the line is 
First, you must find 2 points.
(-6,8) (-2,5)
Then, you must substitute the value of the points in.

Finally, simplify the fraction.

Answer:
x=59 y= 81 z= 99
Step-by-step explanation:
z=
180-(57+24)=99
y=180-99=81
x= 40+81=121
180-121=59
Answer:
B
Step-by-step explanation:
A function can be graphed as a straight line, as long as it isn't vertical.
I think the answer would be C because variability means average.
V = 1,005.7 rounded off to one decimal place
Because:
Volume of a cylinder = πr²h
V = 22/7 x 4 x 4 x 20
V = 1,005.7
