You can put this solution on YOUR website!
find the equation of the line that passes through (3,-1) and is perpendicular to the line that passes through (-5,2) and (-1,7).
\n" ); document.write( "----------
\n" ); document.write( "Step 1, find the slope of the line thru the points.
\n" ); document.write( "Step 2, lines perpendicular have a slope that's the negative inverse.
\n" ); document.write( "step 3, use
\n" ); document.write( "-----
\n" ); document.write( "y-y1 = m*x-x1) where m = slope and (x1,y1) is the point (3,-1)
\n" ); document.write( "-----------
\n" ); document.write( "I'll do a similar problem:
\n" ); document.write( "**************
\n" ); document.write( "find the equation of the line that passes through (2,-2) and is perpendicular to the line that passes through (-1,3) and (-2,-3).
\n" ); document.write( "----------
\n" ); document.write( "find the slope of the line m1
\n" ); document.write( "m1 = diffy/diffx = -6/-1 = 6
\n" ); document.write( "Slope of lines perpendicular m2 = -1/m1 = -1/6
\n" ); document.write( "*************
\n" ); document.write( "y+2 = (-1/6)*(x-2)
\n" ); document.write( "PS It's not \"the equation,\" it's an equation.
