A given line has the equation 2x+12y= -1
What is the equation in slope intercept form of the line that is perpendicular to the given line and passes through the point (0,9)

Answer :

Hrishii

Step-by-step explanation:

Equation of the given line is :

[tex] 2x +12y= - 1\\

\therefore 12y = - 2x - 1\\

\therefore y = \frac {- 2}{12}x - \frac {1}{12}\\

\therefore y = - \frac {1}{6}x - \frac {1}{12}\\[/tex]

Equating above equation with [tex] y= m_1x + c

[/tex] we find:

[tex] m_1 = - \frac{1}{6}[/tex]

Where [tex] m_1[/tex] is the slope of given line:

Let the slope of required line be [tex] m_2.[/tex]

Since lines are perpendicular

[tex] \therefore m_1 \times m_2= - 1\\

\\\therefore - \frac{1}{6} \times m_2= - 1\therefore m_2= 6\\[/tex]

Equation of required line in slope point form is given as:

[tex] y-y_1 =m_2(x-x_1) \\

\therefore y-9 =6(x-0)\\

\therefore y-9 =6x\\

\huge\orange {\boxed {\therefore y =6x+9}} \\[/tex]

Answer: A. Y= -6x+9
