For the line 3x+2y-5=0, find the obtuse angle the line that makes with the positive direction of the x-axis.
\n" ); document.write( "-----------
\n" ); document.write( "Step 1, find the slope of the given line. Call it $\"m%5B1%5D\"$
\n" ); document.write( "Step 2, lines perpendicular have a slope that's the negative inverse. = $\"-1%2Fm%5B1%5D\"$ Call it $\"m%5B2%5D\"$
\n" ); document.write( "Step 3, use $\"y-y%5B1%5D+=+m%5B2%5D%2A%28x+-+x%5B1%5D%29\"$ Where (x1,y1) is the point.
