How do I write a slope-intercept for a line passing throught the given point that is parallel to the given line (7,-3); 8x+7y=4?
\n" ); document.write( "---
\n" ); document.write( "That equation has slope = -8/7
\n" ); document.write( "Form:: y = mx + b
\n" ); document.write( "Solve for \"b\"::
\n" ); document.write( "-3 = (-8/7)7 + b
\n" ); document.write( "b = 5
\n" ); document.write( "----
\n" ); document.write( "Equation:
\n" ); document.write( "y = (-8/7)x+5
\n" ); document.write( "----------------------\r
\n" ); document.write( "\n" ); document.write( " How do I write a second equation that's perpendicular to the given line?
\n" ); document.write( "slope you want is +7/8
\n" ); document.write( "----
\n" ); document.write( "Form:: y = mx + b
\n" ); document.write( "Solve for \"b\"::
\n" ); document.write( "-3 = (7/8)7 + b
\n" ); document.write( "-24/8 = 49/8 + b
\n" ); document.write( "b = -73/8
\n" ); document.write( "-----
\n" ); document.write( "Equation:
\n" ); document.write( "y = (7/8)x-(73/8)
\n" ); document.write( "------------
