Respuesta :
(y - 1) = 1/4(x - 12)
4(y - 1) = x - 12
4y - 4 = x - 12
x - 4y = -4 + 12
x - 4y = 8
4(y - 1) = x - 12
4y - 4 = x - 12
x - 4y = -4 + 12
x - 4y = 8
Answer: The correct option is
(A) [tex]x-4y=8.[/tex]
Step-by-step explanation: Given that the point-slope form of the equation of the line passing through the points (-4, -3) and (12, 1) is given by
[tex]y-1=\dfrac{1}{4}(x-12)~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
We are to select the correct standard form of the equation for the above line.
From equation (i), we have
[tex]y-1=\dfrac{1}{4}(x-12)\\\\\\\Rightarrow 4(y-1)=x-12\\\\\Rightarrow 4y-4=x-12\\\\\Rightarrow x-12-4y+4=0\\\\\Rightarrow x-4y-8=0\\\\\Rightarrow x-4y=8.[/tex]
Thus, the required standard form of the equation of the line is
[tex]x-4y=8.[/tex]
Option (A) is CORRECT.
