Algebra.Com's Answer #191813 by richwmiller(17219)![]() ![]() You can put this solution on YOUR website! I have no idea what you were trying to do. \n" ); document.write( "We want an equation that looks something like y=2x+4 \n" ); document.write( "but with different numbers \n" ); document.write( "It is modeled after y=mx+b where m is the slope and b is the value of y when x=0 \n" ); document.write( "So we are told that m=-1/5 \n" ); document.write( "and we have the point (-2,0) \n" ); document.write( "so we need to find b \n" ); document.write( "0=-1/5*(-2)+b \n" ); document.write( "0=2/5+b \n" ); document.write( "-2/5=b \n" ); document.write( "So our equation is y=-1x/5-2/5 \n" ); document.write( "We could get rid of the fractions but we are told to leave it this way. \n" ); document.write( "so we know the point (0,-2/5) and the point given us (-2,0)\r \n" ); document.write( "\n" ); document.write( "The slope m tells us that for every 1 that y goes up x goes down 5 \n" ); document.write( "It also tells us that for every 1 that y goes down x goes up 5. \n" ); document.write( "So from point (-2,0) we can find a point (-7,1) or (3,-1) \n" ); document.write( " \n" ); document.write( " |
