Algebra.Com's Answer #30767 by tutorcecilia(2152)![]() ![]() You can put this solution on YOUR website! First Method: \n" ); document.write( "(y-y2)=m(x-x2) [Use the point-slope format] \n" ); document.write( "y-(-2)=(3/7)(x-9) [Plug-in the given values: m=(3/7) and points-(9, -2) \n" ); document.write( "y+2=3/7x-(27/7) [Solve for y] \n" ); document.write( "y=(3/7)x-(27/7)-2 \n" ); document.write( "y=(3/7)x-(41/7) [Final answer] \n" ); document.write( ". \n" ); document.write( ". \n" ); document.write( "Second Method: \n" ); document.write( "y=mx+b [Use the slope-intercept format] \n" ); document.write( "(-2)=(3/7)(9)+b [Plug-in the given values: m=(3/7) and points-(9, -2) \n" ); document.write( "-2=(27/7) + b [Solve for \"b\"] \n" ); document.write( "(-14-27)/7 = b [Simplify] \n" ); document.write( "-41/7 = b \n" ); document.write( "y=(3/7)x-(41/7) [Plug-in the values for \"m\" and \"b\"][final answer]\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
