Find the slope of any line perpendicular to the line through points (0, 5) and
\n" ); document.write( "(-3, -4).
\n" ); document.write( "First we need to find the slope between these two points:
\n" ); document.write( "The slope formula is what you use when you are given two points (x1,y1) and (x2,y2). $\"highlight%28m=%28y2-y1%29%2F%28x2-x1%29%29\"$ . (m stands for slope)
\n" ); document.write( " $\"m=%28-4-5%29%2F%28-3-0%29\"$
\n" ); document.write( " $\"m=-9%2F-3\"$
\n" ); document.write( " $\"m=3%2F1\"$ or m=3
\n" ); document.write( "Perpendicular lines have slopes that are negative reciprocals of each other. (change the sign and flip the slope upsidedown.)
\n" ); document.write( "The slope of any line perpendicular to the line through those points is:
\n" ); document.write( " $\"highlight%28m=-1%2F3%29\"$
