Answer:
x = - 10
Step-by-step explanation:
Average is calculated as
average = , thus
= 3
Multiply both sides by 3 to clear the fraction
19 + x = 9 ( subtract 19 from both sides )
x = - 10

<h3>What is a linear function?</h3>The slope-intercept representation of a linear function is given by the rule presented as follows:
y = mx + b
The coefficients of the function and their meaning are explained as follows:
- m is the slope of the function, representing the change in the output variable y when the input variable x increases by one.
- b is the y-intercept of the function, representing the numeric value of the function when the input variable x assumes a value of 0.
In this problem, the function is given as follows:
y + 20 = -2x.
In slope-intercept format, the function is:
y = -2x - 20.
This means that:
- When the longitude is of 0, the latitude is of 20. (passing through Mali).
- Due to the negative slope, the line is decreasing.
Hence the line is presented on the image given at the end of the answer.
