How do you write the equation of a line in slope intercept form that is parallel to the line #y=1/3x+5# and passes through (-9, 5)?
If you have the slope of a line,
Let's find the slope first. If two lines are perpendicular, then the one slope is the negative reciprocal of the other.. ie
The line we want to know about is perpendicular to a line with a slope of
