Answer:

Step-by-step explanation:
We can model this function using the equation of a line:

Where a is the slope of the line and b is the y-intercept.
To find the values of a and b, we can use the two points given:
(-9, -3):


(-12, 4):


If we subtract the second equation from the first one, we have:




Then, finding the value of b, we have:



So the equation is:

Answer:
I think it is 3.5
Step-by-step explanation:
8.5:250*100 =
(8.5*100):250 =
850:250 = 3.4
L = (1⅕)W= (6/5)W
LW = 480 in²
(6/5)W² = 480
W² = 480 × ⅚ = 400
W = 20 in
L = (6/5)W =24 in
