Algebra.Com's Answer #288210 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! I understand that y=mx+b \n" ); document.write( "5= -2(-1)+b \n" ); document.write( "b=3 right?? \n" ); document.write( "----------------- \n" ); document.write( "That's right. Now you know the slope, m and the y-int, b \n" ); document.write( "So y = mx + b \n" ); document.write( "y = -x + 3 is the equation of the line. \n" ); document.write( "------------ \n" ); document.write( "Pick 2 values for x and find y \n" ); document.write( "x = 0, y = 3 --> (0,3) \n" ); document.write( "x = 3, y = 0 --> (3,0)\r \n" ); document.write( "\n" ); document.write( "Plot the two points, draw a line thru them \n" ); document.write( " \n" ); document.write( " |
