Algebra.Com's Answer #9240 by jakegfan(4)![]() ![]() ![]() You can put this solution on YOUR website! Okay the slope intercept form is y=mx+b\r \n" ); document.write( "\n" ); document.write( "To find the slope or m \n" ); document.write( "you take the y out of the second set of number subtracted by the y in the first set of numbers then divide it by x out of the second set of numbers subtracted by the first x of the first set of numbers it will look like this\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "7-5/2-1 or 2 over 1 or 2\r \n" ); document.write( "\n" ); document.write( "so far you have y=2x+b\r \n" ); document.write( "\n" ); document.write( "then you have to figure out b\r \n" ); document.write( "\n" ); document.write( "so you plug in coordinates \n" ); document.write( "5=2(1)+b \n" ); document.write( "5=2+b\r \n" ); document.write( "\n" ); document.write( "you take 5 subtracted by 2\r \n" ); document.write( "\n" ); document.write( "so 3=b\r \n" ); document.write( "\n" ); document.write( "so your equation is y=2x+3 \n" ); document.write( " \n" ); document.write( " |
