Algebra.Com's Answer #739110 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! Several ways. \n" ); document.write( "let x=0 and y=-1, so (0, -1) is one point. \n" ); document.write( "Now let y=0 and 3x=-1, so x=-(1/3) and (-1/3, 0) is another point. \n" ); document.write( "Draw a line between the two points.\r \n" ); document.write( "\n" ); document.write( "Slope-intercept form of y=mx+b where m is the slope (rise/run) and b the y-intercept, or where x=0. \n" ); document.write( "move the 3x to the right \n" ); document.write( "y=-3x-1 \n" ); document.write( "line has y-intercept of -1, so (0, -1) is a point. \n" ); document.write( "slope is -3. \n" ); document.write( "From -1 go right 1 and down 3 or left 1 and up 3. Draw a line. \n" ); document.write( " |
