Hello, \n" ); document.write( "The slope of a line is found as follows of the two points (-5,-18)(-9,-19).\r \n" ); document.write( "\n" ); document.write( " (y - y)/(x - x) \n" ); document.write( "so let's take the first y (-18) and subtract the second y(-19). \n" ); document.write( "It'll look like this: -18 - (-19) When you have two negatives sign together it makes a positive. (+) \n" ); document.write( "So this will be -18 + 19 = 1 \n" ); document.write( "Now, let's look at the x's. \n" ); document.write( "-5 - (-9) = +4 \n" ); document.write( "The slope is 1/4 \n" ); document.write( "Just as a note you could start with with the other y first -19 - (-18) = -1 \n" ); document.write( "And use the same pattern with x's. -9 -(-5) = -4 \n" ); document.write( "That gives us -1/-4 but when you have two negatives it turns positive and we come up with the same answer 1/4 \n" ); document.write( "RJ Toftness \n" ); document.write( "www.math-unlock.com \n" ); document.write( " |
