Algebra.Com's Answer #13607 by Died2Soon(6)![]() ![]() ![]() You can put this solution on YOUR website! the Problem is: 3x+5y=15 \n" ); document.write( "First subtract the 3x from both sides like this: 3x-3x+5y=15-3x \n" ); document.write( "you should get: 5y=-3x+15 because th 3x and the -3x cancel each other out \n" ); document.write( "Now divide both sides by 5, like this: 5y/5=(-3x+15)/5 \n" ); document.write( "Now you should get: y=-3/5x+3 \n" ); document.write( "the slope is: -3 over 5 \n" ); document.write( "The Y-Intercept is: 3 \n" ); document.write( "So find 3 on the Y axis and put a point on that spot. Now go down 3 spaces and to the right 5 spaces, because the slope is -3 over 5. You can also reverse this and go up 3 and 5 to the left.\r \n" ); document.write( "\n" ); document.write( "Hope this helps \n" ); document.write( "=) \n" ); document.write( " |
