Algebra.Com's Answer #127573 by KnightOwlTutor(293)![]() ![]() You can put this solution on YOUR website! The general equation of a line is y=mx+b \n" ); document.write( "We already that m=-4 so let's plug that in\r \n" ); document.write( "\n" ); document.write( "y=-4x+b\r \n" ); document.write( "\n" ); document.write( "We need to find the value of b to make the equation correct.\r \n" ); document.write( "\n" ); document.write( "Replace the variable x and y with the point value.\r \n" ); document.write( "\n" ); document.write( "1=-4(1)+b\r \n" ); document.write( "\n" ); document.write( "1=-4+b\r \n" ); document.write( "\n" ); document.write( "Add 4 to both sides\r \n" ); document.write( "\n" ); document.write( "5=b\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Thus the equation is y=-4x+5\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Let's doublecheck\r \n" ); document.write( "\n" ); document.write( "1=-4+5\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "1=1 \n" ); document.write( " |
