Answer:
-1/6
Step-by-step explanation:
Slope=change in y/change in x
Y-values: 8 and -4
X-values: 4 and 2
Change is the difference in position (subtract)
8- (-4)/(4-2)=12/2=6 = first slope
Perpendicular lines have opposite reciprocal slope

Answer: 3 positive integers.
Step-by-step explanation:
This can be translated to:
"how many integer numbers have the same number of digits in their cubes and squares?"
for example, a number that will be an option is 2:
Because 2*2 = 4
2*2*2 = 8
the square and cube of 2 have the same number of digits.
3 for example:
3*3 = 9
3*3*3 = 27
does not match the condition.
1 does match it, obviusly.
0 is not positive, so we can ignore it.
let's see 4.
4*4 = 16
4*4*4 = 64
So 4 is other number that matches the condition.
Now, 5:
5*5 = 25
5*5*5 = 125
5 does not match the condition, and any number upper than 5 also does not match the condition.
so the numbers we have are 1, 2 and 4.
so we have 3 integers.
Answer:

$121.00, $127.00, $133.00/share?
If so then
Step by step explanation:
20×121=2420 (-40)
20×127=2540 (-40)
242+254=4960 (-80)
40×133=5320 (-40)
5320-40-4960+80=5280-4960+80=320+80=400
