Algebra.Com's Answer #665906 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! Find an equation for the line that satisfies the conditions. \n" ); document.write( "1. Slope 2; passing through (4,12) \n" ); document.write( "Use \n" ); document.write( "y-y1 = m*(x-x1) where m = slope and (x1,y1) is the point. \n" ); document.write( "y-12 = 2*(x-4) \n" ); document.write( "That's it. \n" ); document.write( "==================== \n" ); document.write( "2. Passing through (0,15) and (5,3) \n" ); document.write( "Step 1 find the slope, m \n" ); document.write( "m = diffy/diffx = (15-3)/(0-5) \n" ); document.write( "m = -12/5 \n" ); document.write( "-------------- \n" ); document.write( "Now same as #1, using either point. \n" ); document.write( "y-15 = (-12/5)*(x-0) \n" ); document.write( "y-15 = -12x/5 \n" ); document.write( "------------ \n" ); document.write( "There are only a few things to remember. \n" ); document.write( "The slope, m, is obvious. It's the change in y divided by the change in x. \n" ); document.write( " \n" ); document.write( " |
