| Algebra.Com's Answer #40416 by uma(370)      You can put this solution on YOUR website! Given equation is 2x - 3y = 24 \n" ); document.write( "To find the y inyercept we put x = 0, \n" ); document.write( "==> -3y = 24 or y = -8{dividing by 3] \n" ); document.write( "So the first point is (0, -8)\r \n" ); document.write( "\n" ); document.write( "5x + 6y = 30 \n" ); document.write( "Replacing y by 0 we get, \n" ); document.write( "5x = 30 or x = 6[dividing by 5] \n" ); document.write( "So the second point is (5,0)\r \n" ); document.write( "\n" ); document.write( "Equation of a line through 2 points (x1,y1) and (x2,y2) is (y-y1)/(x-x1)= (y2-y1)/(x2-x1)\r \n" ); document.write( "\n" ); document.write( "Applying that for our points we get,\r \n" ); document.write( "\n" ); document.write( "(y+8)/(x-0) = (0+8)/(6+0) \n" ); document.write( "==> (y+8)/x = 8/6 \n" ); document.write( "==> (y+8)/x= 4/3 \n" ); document.write( "On simplification we get, 3y + 24 = 4x \n" ); document.write( "Or 3y = 4x - 24 \n" ); document.write( " |
