Algebra.Com's Answer #185380 by richwmiller(17219)![]() ![]() You can put this solution on YOUR website! Cut the bull. Everyone who submits a problem wants help and doesn't understand the problem. \n" ); document.write( "Your situation and problem are not unique. \n" ); document.write( "Actually it is quite basic. \n" ); document.write( "You should be asking yourself why you don't understand. Where were you when it was explained? Where is the book that explains it? Where are your notes? \n" ); document.write( "We are here to teach and you to learn not for us to do your homework. \n" ); document.write( "Write an equation with slope and point is very common. \n" ); document.write( "You have to do several things. \n" ); document.write( "First, find the slope of the linear equation you were given \n" ); document.write( "Ask yourself what the slope would be of a line perpendicular to this one \n" ); document.write( "Lines which are perpendicular have slope whose product is -1 \n" ); document.write( "so if one slope is 1/2 the other slope will be -2 \n" ); document.write( "1/2*-2=-1 \n" ); document.write( "so the other slop=e will be its negative(minus) reciprocal fraction turned over.2/1 turned over becomes 1/2 \n" ); document.write( "1/2 turned over becomes 2/1 \n" ); document.write( "Where m is the slope and b is the y intercept when x=0\r \n" ); document.write( "\n" ); document.write( "We are lucky that the given equation is in the right format. \n" ); document.write( "y=3x+2 \n" ); document.write( "The slope is 3 and we want the negative reciprocal -1/3 \n" ); document.write( "so our equation is starting \n" ); document.write( "y=-x/3+b \n" ); document.write( "Now we need to find b \n" ); document.write( "so we plug in the point we were given \n" ); document.write( "-3,5 \n" ); document.write( "where x=-3 and y=5 \n" ); document.write( "y=-x/3+b \n" ); document.write( "5=-(-3)/3+b \n" ); document.write( "5=3/3+b \n" ); document.write( "5=1+b \n" ); document.write( "4=b \n" ); document.write( "now we put it altogether and here is our equation \n" ); document.write( "y=-x/3+4 \n" ); document.write( " \n" ); document.write( " |
