The mean temperature of the given data − 3 , 0 , 10 , 2 , 8 , − 5 , − 1 , 9 , 2 , − 3 is 1.9
mean= 1.9
<h3>What is mean of the data?</h3>The mean, or average, is calculated by adding up the data and dividing by total number of data.
Given data: − 3 , 0 , 10 , 2 , 8 , − 5 , − 1 , 9 , 2 , − 3
Now, mean =
mean =
=
mean= 1.9
Hence, the mean of − 3 , 0 , 10 , 2 , 8 , − 5 , − 1 , 9 , 2 , − 3 is 1.9

Answer:
<h2>7x - 4y + 18 = 0</h2>Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
========================================
Let
========================================
We have the equation of a line in a general form (Ax + By + C = 0)
Convert it to the slope-intercept form:
<em>subtract 7y from both sides</em>
<em>divide both sides by (-7)</em>
Therefore
We have the equation:
Put the coordinates of the point (-2, 1) to the equation, and solve for <em>b</em> :
<em>multiply both sides by 2</em>
<em>add 7 to both sides</em>
<em>divide both sides by 2</em>
[te]x\dfrac{9}{2}=b\to b=\dfrac{9}{2}[/tex]
Finally:
- <em>slope-intercept form</em>
Convert to the general form:
<em>multiply both sides by 4</em>
<em>subtract 4y from both sides</em>
