Algebra.Com's Answer #66168 by checkley71(8403) ![]() You can put this solution on YOUR website! slope=(5-2)/(-4+3)=3/-1=-3. \n" ); document.write( "now supstitute one set of coordinates in the line equation with a slope of -3 & solve for the y intercept(b) \n" ); document.write( "2=-3*-3+b \n" ); document.write( "2=9+b \n" ); document.write( "b=2-9 \n" ); document.write( "b=-7 thus the equation is \n" ); document.write( "y=-3x-7 or answer B). \n" ); document.write( " |
