Algebra.Com's Answer #520603 by rothauserc(4718)![]() ![]() You can put this solution on YOUR website! The standard form for a line is y = mx + b, where m is the slope and b is the y intercept \n" ); document.write( "m is defined as (y2 - y1) / (x2 - x1) \n" ); document.write( "for our problem m = ( 1 - 2) / (5 - (-2)) = -1 / 7 \n" ); document.write( "y = -x/7 + b \n" ); document.write( "now take point (-2, 2) and substitute in the equation above to find b \n" ); document.write( "2 = -(-2)/7 + b \n" ); document.write( "2 = 2/7 + b \n" ); document.write( "b = 14/7 - 2/7 = 12/7 \n" ); document.write( "y = -x/7 + 12/7 \n" ); document.write( "here is a graph of the line \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " |
