Question 812136: Find a equation of the line. Write the equation using function notation.
through(5,-3); perpendicular to 3y=x-6
Answer by TimothyLamb(4379)   (Show Source):
You can put this solution on YOUR website! perpendicular lines have negative reciprocal slopes:
---
3y = x - 6
y = (1/3)x - 2
---
the perp line has slope -3
---
user point-slope form: y - y1 = m(x - x1)
with slope = -3
point = (5, -3)
---
y - y1 = m(x - x1)
y + 3 = -3(x - 5)
y + 3 = -3x + 15
---
f(x) = -3x + 12
