Algebra.Com's Answer #74108 by doukungfoo(195)![]() ![]() You can put this solution on YOUR website! Writing the equation for a line in slope intercept form is just a matter of setting the equation equal to y \n" ); document.write( "So for \n" ); document.write( "x + y = 5 \n" ); document.write( "move the x to the other side of the equation by subtracting x from both sides \n" ); document.write( "x - x + y = 5 - x \n" ); document.write( "y = 5 - x \n" ); document.write( "Now for slope intercept form when need the x to be placed directly after the equal sign. so lets make that adjustment \n" ); document.write( "y = -x + 5 \n" ); document.write( "Ok so now we have x + y = 5 written in slope intercept form y = mx + b \n" ); document.write( "m is the slope \n" ); document.write( "and b is the y intercept \n" ); document.write( "so in our equation \n" ); document.write( "y = -x + 5 \n" ); document.write( "the slope is -1 or -1/1 \n" ); document.write( "and the y intercept is 5 \n" ); document.write( " |
