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

0.2(6x+1)/3.6=0.5x/9
Zinaida [17]

0.2(6x+1)/3.6=0.5x/9

Solution

(1.2x + 0.2)/3.6 = 0.5x/9

Cross multiplying, we get

9(1.2x + 0.2) = 3.6 * 0.5x

10.8x + 1.8 = 1.8x

10.8x - 1,8x = -1.8

9x = -1.8

Dividing both sides by 9, we get

x = - 0.2

That's the answer.

Thank you.
