The slope would be - 1/2 !!
you would number the x and y values of the coordinates.
( -2 , 5 ) ( -6 , 7 )
x1. y1. x2. y2
then do the formula that gives you the slope y2 - y1 / x2 - x1
this gives you:
7 - 5 / -6 - (-2) = 2/ -4 (simplify) -1/2
so this would give you m= -1/2
8 * 3/4 = 24/4
24/4 = 6
The answer is 6.
Hope this helped☺☺

Answer:
5
Step-by-step explanation:
The formula for Standard Error =
Standard deviation /√n
Where
n = Random number of samples
From the above question,
Standard deviation = 10
n = 4
Hence, Standard Error is calculated as:
= 10/√4
= 10/2
= 5
Therefore, the Standard error = 5
Given:
and 
.
To find:
Whether 
is possible or not.
Solution:
We have,
(CPCTC)
...(i)
And,
...(ii) (Vertically opposite angles)
From (i) and (ii), we get
...(iii)
Now,
(Linear pair)
(Using (iii))
Divide both sides by 2.
The measure of angle 1 is 49 degrees so it cannot be equal to 47 degrees.
Therefore, the required answer is "no", the given statement is not possible.
