New amount - original amount = amount of change
amount of change/original amount × 100 = percent of change
<span>-----------------------------------------------------------------------------
</span>
36 - 34.5 = 1.5
<span>1.5/34.5 × 100 = 4%</span>
Divide by 6 is the same as times 1/6
-2 and 1/2=-10/2-1/2=-11/2
-11/2 times 1/6=-11/12
<span>
The first point is (x1,y1). The second point is (x2,y2)
Since the first point is (-1, -3), we can say (x1, y1) = (-1, -3)
So ,
Since the second point is (-4, -8), we can also say (x2, y2) = (-4, -8)
So ,
Put this all together to get: , , , and </span>
Assuming the order of selection doesn't matter:
