(-3, -15) and is perpendicular to -6x + 8y = 3. Thank you.
\n" ); document.write( "-6x+8y = 3
\n" ); document.write( "Find the slope of this line
\n" ); document.write( "8y=6x-3
\n" ); document.write( "Divide by 8
\n" ); document.write( "y= 3/4x-0.38
\n" ); document.write( "Compare this equation with y=mx+b
\n" ); document.write( "slope m =0.75
\n" ); document.write( "The slope of a line perpendicular to the above line will be the negative reciprocal = -1.33
\n" ); document.write( "(m1*m2=-1) m=
\n" ); document.write( "-1.33 ,point( -3,-15)
\n" ); document.write( "Find b by plugging the values of m & the point in
\n" ); document.write( "y=mx+b
\n" ); document.write( "-15=4.00 +b
\n" ); document.write( "b=-19
\n" ); document.write( "m=-1.33
\n" ); document.write( "The required equation is y=-1.33x -19
