Algebra.Com's Answer #115282 by nerdybill(7384) You can put this solution on YOUR website! I think they are giving you two points on a line and they are asking you to find the slope. \n" ); document.write( ". \n" ); document.write( "Reviewing this site should help: \n" ); document.write( "http://www.algebralab.org/lessons/lesson.aspx?file=Geometry_CoordSlope.xml \n" ); document.write( ". \n" ); document.write( "Two points are: \n" ); document.write( "(8,8) and (-7,-4) \n" ); document.write( ". \n" ); document.write( "The generalized form of a slope given two points is: \n" ); document.write( "m = (y1-y2)/(x1-x2) \n" ); document.write( "where \n" ); document.write( "m is the slope \n" ); document.write( ". \n" ); document.write( "If \n" ); document.write( "(x1,y1) = (8,8) \n" ); document.write( "and \n" ); document.write( "(x2,y2) = (-7,-4) \n" ); document.write( ". \n" ); document.write( "then: \n" ); document.write( "m = (y1-y2)/(x1-x2) \n" ); document.write( "m = (8-(-4))/(8-(-7)) \n" ); document.write( "m = (8+4)/(8+7) \n" ); document.write( "m = 12/15 \n" ); document.write( "m = 4/5 (this is the slope)\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
