Question

A student finds the slope of the line between (8,17,) and (1,4) she writes 17-4/1-8 What mistake did she make?

Answer 1

The mistake did she make are like about the first term (8,17),like 8,as x1,and 17 as y1,,,,,,the second term:(1,4),,,like 1 as x2,,,and 4 as y2,,,,,soooo based on the formula slope;M=y2-y1\x2-x1,,,,sooo M= 4-17\1-8 sooo -13\-7 so multiply by (-1) on both sides,,, the answer is m= 13\7 or by divided it that be 1.86.....
