Algebra.Com's Answer #776600 by greenestamps(13203)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "I prefer to use my understanding of slope, rather than a mathematical formula, to solve problems like this. \n" ); document.write( "I also encourage students to do that, since it helps gain an understanding of slope, whereas plugging numbers into a formula does not. \n" ); document.write( "(Furthermore, if you plug the numbers in the wrong places in the formula, you probably won't get the right answer....) \n" ); document.write( "The second of the two given points is 10 to the right of the first. \n" ); document.write( "Since the slope is -1/5, the second point must be 2 down from the first. \n" ); document.write( "2 down from the first, ending at -7, means the y coordinate of the first point is -5. \n" ); document.write( "ANSWER: k = -5 \n" ); document.write( " \n" ); document.write( " |
