Answer:

Explanation:
Given:
line y=3x-1
point (-3,0)
Write: equation of the line that is perpendicular to the given and passes through the point (-3,0)
Solution:
The slope of the given line is

If
is the slope of perpendicular line, then

So, the equation of the needed line is

Find b. This line passes through the point (-3,0), so its coordinates satisfy the equation:
