It will take 40 meters for Amir to reach sea level because the linear function is y = -10x + 40.
What is a straight line?
A straight line is a combination of endless points joined on both sides of the point.
We have a line graph shown in the picture that represents:
Altitude relative to sea level (in meters) as a function of time (in minutes) is graphed.
First find the function which will be a linear function.
y = mx + c
m is the slope of the linear function:
AS we know, the ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
The linear function will be:
(36, 40) and (40, 0)
y = (0-40)/(40-36)[x - 40]
y = -10(x - 40)
y = -10x + 40
Plug x = 0(for sea level)
y = 40 meters
Thus, it will take 40 meters for Amir to reach sea level because the linear function is y = -10x + 40.
