Step-by-step explanation:
Ответ:
let
step![1](/tex.php?f=1)
find the slope of the line ab
we know that
the formula to calculate the slope between two points is equal to
substitute the values
step![2](/tex.php?f=2)
find the equation of the line ab with the slope m and point a
we know that
the equation of the line in the slope-point form is equal to
substitute the values
convert to function form
let
therefore
the answer is the option
see the attached figure to better understand the problem
