Worth 50 pointsss what is the equation of a line that is perpendicular to −x+3y=9 and passes through the point (−3, 2) ? enter your equation in the box.

We know that if two lines are Perpendicular then Product of Slopes of both of these Perpendicular lines should be Equal to -1

Given : Equation of 1st Perpendicular line is -x + 3y = 9

This can be written as :

3y = x + 9

y = x/3 + 3

Comparing with standard form : y = mx + c

we can notice that slope of 1st Perpendicular line = 1/3

Slope of 1st Line × Slope of 2nd line = -1

1/3 × Slope of 2nd line = -1

Slope of 2nd line = -3

We know that the form of line passing through point (x₀ , y₀) and having slope m is :

y - y₀ = m(x - x₀)

Here the 2nd Perpendicular line passes through the point (-3 , 2)

x₀ = -3 and y₀ = 2 and we found m = -3

⇒ y - 2 = -3(x + 3)

⇒ -3x - 9 = y - 2

⇒ -3x - y = 7

answer is x<
