Which is the equation of the line through the point (−3, 8) that is perpendicular to the line y=14x+12? CLEAR SUBMIT y=−14x−5 y=−4x−4 y=−4x+35 y=4x+29

Respuesta :

Answer: [tex]x+14y=109[/tex]

Step-by-step explanation:

Given

The line passes through [tex](-3,8)[/tex] and is perpendicular to the given line [tex]y=14x+12[/tex]

Comparing [tex]y=14x+12[/tex] with line [tex]y=mx+c[/tex] to get the slope i.e. [tex]\text{Slope=}14[/tex]

Suppose m is the slope of the required line

And the product of the slope of perpendicular lines is [tex]-1[/tex]

[tex]\therefore 14(m)=-1\\\\\Rightarrow m=-\dfrac{1}{14}[/tex]

The equation of the required line is

[tex]\Rightarrow \dfrac{y-8}{x+3}=-\dfrac{1}{14}\\\\\Rightarrow -14y+14\times 8=x+3\\\Rightarrow x+14y=112-3\\\Rightarrow x+14y=109[/tex]

None of the given options is correct.
