Algebra.Com's Answer #38254 by stanbon(75887) ![]() You can put this solution on YOUR website! Where does the line -3x-4y=-12 intesect the x-axis? \n" ); document.write( "The x-axis is where y=0. \n" ); document.write( "So, let y=0 in your equation and solve for x. \n" ); document.write( "You get -3x-4(0)=-12 \n" ); document.write( "-3x=-12 \n" ); document.write( "x=4 ; that is the x -intercept. \n" ); document.write( "------------------------ \n" ); document.write( "Where does the line intersect the y-axis \n" ); document.write( "The y-axis is where x=0. \n" ); document.write( "So let x=0 in your equation and solve for y. \n" ); document.write( "You get -3(0)-4y=-12 \n" ); document.write( "-4y=-12 \n" ); document.write( "y=3 ; that is the y-intercept \n" ); document.write( "----------- \n" ); document.write( "What is the slope? \n" ); document.write( "To find the slope put the equation in the slope-intercept form \n" ); document.write( "as follows: \n" ); document.write( "-3x-4y=-12 \n" ); document.write( "Multiply thru by -1 to get: \n" ); document.write( "3x+4y=12 \n" ); document.write( "4y=-3x+12 \n" ); document.write( "y=(-3/4)x+3 \n" ); document.write( "The slope is -3/4 \n" ); document.write( "-------------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
