Answer:

The equation of the line that passes through the point (-2,7) and is perpendicular to the line x-6y=42 is

[tex]6x+y=-5[/tex]

Step-by-step explanation:

Given:  

Let,  

point A( x₁ , y₁) ≡ ( -2 , 7)

To Find:  

Equation of Line  that passes through the point (-2,7) and is perpendicular to the line x-6y=42=?  

Solution:  

[tex]x-6y=42[/tex]    ..................Given

which can be written as

[tex]y=mx+c[/tex]

Where m is the slope of the line

∴ [tex]y=\dfrac{x}{6}-7[/tex]

On Comparing we get

[tex]Slope = m = \dfrac{1}{6}[/tex]

The Required line is Perpendicular to the above line.

So,

Product of slopes = - 1

[tex]m\times m_{1}=-1\\Substituting\ m\\ \dfrac{1}{6} m_{1}=-1\\\\m_{1}=-6[/tex]

Slope of the required line is -6

Equation of a line passing through a points A( x₁ , y₁) and having slope m is given by the formula,  

i.e equation in point - slope form

[tex](y-y_{1})=m(x-x_{1})[/tex]

Now on substituting the slope and point A( x₁ , y₁) ≡ ( -2, 7) and slope = -6 we get

[tex](y-7)=-6(x--2)=-6(x+2)=-6x-12\\\\\therefore 6x+y=-5.......is\ the required\ equation\ of\ the\ line[/tex]

The equation of the line that passes through the point (-2,7) and is perpendicular to the line x-6y=42 is

[tex]6x+y=-5[/tex]
