My name is Crystal and I am in 9th grade algebra. We are currently studying parallel and perpendicular lines. I am having trouble with this problem: 3/4x - 5y= 16, (5,-6) I have to find a line that is perpindicular to this line on a graph.
The crutial fact you need to use about perpendicular lines is that if a line had slope m then any line perpendicular to it has slope -1/m. The first job here is to find the slope of the line 3/4x - 5y = 16.
