Question

can someone help me please
find an equation of the line. write the equation using function notation.
through (4,-9); perpendicular to 3y=x-6

Answer 1

3y=x-6
\[y=\frac{ 1 }{ 3 }x-2\]
its slope=1/3
slope of line perpendicular to it=-3
reqd line is\[y-(-9)=-3(x-4)\]
simplify it.

Answer 2

so, y+9=-3x+12?

Answer 3

y+-3x+3?

Answer 4

y=-3x+3

Answer 5

correct
