Answer:
is the equation of perpendicular line.
Step-by-step explanation:
We are given , the equation of a line is 
We can deduce that the slope of the given line is 
The slope of its perpendicular line would be , 
Now using the point slope form, 
Use the given point
substituing these.

Therefore the required equation of a line that is perpendicular to y=-0.3x. +6 and that passes through the point (3,-8) is y=\frac{x}{0.3} -18[/tex]
