Algebra.Com's Answer #763407 by greenestamps(13200)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "You want P to be 2/3 of the way from A to B. \n" ); document.write( "When that is true, the x coefficient of P will be 2/3 of the way from the x coefficient of A to the x coefficient of B, and likewise for the y coefficient of P. \n" ); document.write( "The x coefficients of A and B are 4 and -2, a difference of -6; 2/3 of -6 is -4; the x coefficient of P is 4+(-4) = 0. \n" ); document.write( "The y coefficients of A and B are -2 and -5, a difference of -3; 2/3 of -3 is -2; the y coefficient of P is -2+(-2) = -4. \n" ); document.write( "The point P is P(0,-4). \n" ); document.write( "Your answer is correct. \n" ); document.write( "However, if you used a method from a textbook or some similar resource which uses some sort of mathematical formulas, chances are the work you did to get the answer was more than what I did with my informal common sense approach.... \n" ); document.write( " |
