Answer:
-1/2
Step-by-step explanation:
The question is asking for the slope of the line. The standard form of a linear equation is y=mx+b where m is the slope. To find the slope you simply look at the change in y over the change in x. You can pick any two coordinate points to find the slope.
Here is the equation to find the slope;
****Notice that the line starts up high (looking at it from left to right, like how you read a book), and therefore it is a negative slope.
I am picking the points (-1,2) and (1,1). Plug in the corrdinates- (2-1=1) and (-1-1=-2) -1/2
Hope this helps:)

Answer:
Step-by-step explanation:
Volume of the box = x³ +11x² + 20x – 32 I think the ' is a typo for ³
the width is x-1 and the height is x+8
Find an expression for the length
Vol = LWH solve L
Vol / (WH) = L so
L = (x³ +11x² + 20x – 32) / (x-1) (x+8)
so it would help to factor the numerator
(x³ +11x² + 20x – 32) I'm willing to bet (x-1) and (x+8) are factors
but I will plot the equation to find the three roots
(x³ +11x² + 20x – 32) = (x-1) (x+8) (x+4)
L = (x³ +11x² + 20x – 32) / (x-1) (x+8)
= (x-1) (x+8) (x+4) / (x-1) (x+8) the (x-1) and (x+8) cancel out leaving
L = (x + 4)
