What is the equation of a line that passes through the point (6, 1) and is perpendicular to the line whose equation is y=−2x−6y=
Mandarinka [93]
Lets get the negative reciprocal of the slope so we get
m  =  \frac{1}{2}
Now the equation that is perpendicular is
y =  \frac{1}{2} x + b
Lets solve for b by plugging in the point (x,y)=(6,1)
1 =  \frac{1}{2} (6) + b \\ 1 = 3 + b \\ 1 - 3 = b \\ b =  - 2
Now plug that into the equation. So the equation of the line that is perpendicular and
passes through the point (6, 1) is
y =  \frac{1}{2} x  - 2
