The slope of the line = rise of the line / run of the line = 2/2 = 1.
<h3>How to Find the Slope of a Line?</h3>The slope (m) of a line can be determined by finding the ratio of the rise of the line to the run of the line, which is, the change in y over the change in x.
Referring to the image attached below, the blue line in the given graph shows the rise of the line while the red line shows the run of the line.
Therefore:
Rise of the line = 2 units
Run of the line = 2 units
Slope of the line (m) = rise/run = 2 units/2 units
Slope of the line (m) = 1

Answer:
Standard deviation of given data = 3.16227
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
Given sample size 'n' = 5
Given data 4, 6,8,10,12
Mean of the sample x⁻ = 8
Standard deviation of the sample
<u><em>Step(ii)</em></u>:-
Given data
x : 4 6 8 10 12
x-x⁻ : 4 - 8 6-8 8-8 10-8 12-8
(x-x⁻) : -4 -2 0 2 4
(x-x⁻)² : 16 4 0 4 16
S.D = √10 = 3.16227
<u><em> Final answer</em></u>:-
The standard deviation = 3.16227
