Find an equation for line perpendicular to 2x+6y=18 and goes through the point (8,-1)

y = 3x - 25

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

2x + 6y = 18 ( subtract 2x from both sides )

6y = - 2x + 18 ( divide terms by 6 )

y = - x + 3 ← in slope- intercept form

with slope m = -

Given a line with slope m then the slope of a line perpendicular to it is

= - = - = 3 , then

y = 3x + c ← is the partial equation

To find c substitute (8, - 1 ) into the partial equation

- 1 = 24 + c ⇒ c = - 1 - 24 = - 25

y = 3x - 25 ← equation of perpendicular line

point a is the center of this circle.

the ratio of the lengths of (ef/bc) and (ad/ih) is 2: 1.
