Answer:
-17/5 is we are finding the slope slope of a line containing points:
(1,-6) and (-4,11).
Step-by-step explanation:
Line them up and subtract vertically, then put 2nd difference over first difference.
So you can do it like route 1 or 2 listed below:
Route 1)
( 1 , -6)
- (-4 , 11)
------------
Route 2)
(-4 , 11)
- (1 , -6)
-------------
Let's do Route 1 first:
( 1 , -6)
-(-4 , 11)
------------
5 -17
So the slope is -17/5.
Route 2:
(-4 , 11)
-( 1 ,-6)
------------
-5 17
So the slope is 17/-5 or -17/5 which is what we got doing it route 1 way.
So it doesn't matter which point you put on top.
You could also use this formula directly which is what we did without really stating it:
or 
.
So using this formula directly, you could do either:
or 
So first way gives 17/-5 whereas the second way gives -17/5.
You get the same number either way.
Option fourth "−48; velocity decreases at rate of 48 miles per hour as the time increases" is correct.
<h3>What is the slope?</h3>
The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
We have a function:
v(t) = 352 − 48t
The above function represents the speed of a plane that is landing in the sky.
The function is a linear function.
On comparing with:
y = mx + c
v(t) = -48t + 352
m = -48
-48 is the slope and it representing velocity decreases at rate of 48 miles per hour as the time increases.
Thus, option fourth "−48; velocity decreases at rate of 48 miles per hour as the time increases" is correct.

2. Answer: 35
Step-by-step explanation:
4x3 grid so 4!= 24 and 3!= 6 4+3=7 so 7! = 5040 now 7!/4!*3!=35.
$174.90 / $795 = <em>0.22 </em>(just the naked number, no unit)
