Algebra.Com's Answer #122422 by Mathtut(3670)![]() ![]() ![]() You can put this solution on YOUR website! slope = rise/run or y2-y1/x2-x1 where (x1,y1) and (x2,y2)are points on the line \n" ); document.write( " also lines that are parallel have equal slopes and in order to see the slope in an equation we need to write it in y=mx+b format where m is the slope and b is the y intercept.\r \n" ); document.write( "\n" ); document.write( "1.(5-5)/(7-2)=0 slope =0 which is a horizontal line\r \n" ); document.write( "\n" ); document.write( "2.2x-5y=4 add 5y and subtract 4 to each side 5y=2x-4 divide by 5 y=2/5x-4/5 \n" ); document.write( " therefore slope =2/5 \n" ); document.write( "3.(2-1)/(7-5)=1/2 ---> slope=1/2\r \n" ); document.write( "\n" ); document.write( "4.x=2 undefined slope . this is a vertical line\r \n" ); document.write( "\n" ); document.write( "5.line parallel to 3x-2y=5 add 2y, subtract 5 and divide by 2 on each side \n" ); document.write( " y=3/2x-5/2 slope is 3/2 and since line is parallel also has a slope of 3/2 \n" ); document.write( " |
