Find the slope-intercept form of the line that is perpendicular to −2x+6y=−1 and passes through the point (−2,4)



Answer :

The equation of line that is perpendicular to the given equation and passes through the given point is y = -3x - 2.


What is the equation of line that is perpendicular to −2x+6y=−1 and passes through the point (−2,4)?

Given the equation of line and point;

  • −2x + 6y = −1
  • (-2,4)

First, find the slope intercept form ( y = mx + b )of the given equation to determine the slope.

−2x + 6y = −1

Solve for y

6y = 2x - 1

y = (2/6)x - 1/6

y = (1/3)x - 1/6

Hence, the slope m =  1/3

Now, the equation of a perpendicular line must have a slope that is the negative reciprocal of the original slope.

Slope of the perpendicular will be;

m_perpendicular = -3

Next, find the equation of the perpendicular line using the point slope formula y - y₁ = m( x - x₁ ).

Plug in the slope m = -3 and the point (-2,4).

y - y₁ = m( x - x₁ )

y - 4 = -3( x - (-2) )

y - 4 = -3( x + 2 )

y - 4 = -3x - 6

y = -3x - 6 + 4

y = -3x - 2

Therefore, the equation of line that is perpendicular to the given equation and passes through the given point is y = -3x - 2.
