First you write what the vectors are, then you subtract z from w by subtracting their corresponding values <-4-3,1-4>= <-7,-3>, then to get subtracting the next answer you subtract w from z which is <3--4,4-1> = <7,3>
This differs on what number you want to talk about. 1 is the hundreds, 8 is the tenths, 7 is the ones.
2 divided by 100,000 = 0.00002
Answer:
<h2>
<em>5</em><em>8</em><em>.</em><em>5</em><em> </em><em>dollar</em></h2>

hope this helps..
Good luck on your assignment
It would be: y-y1 = m(x-x1)
y-8 = m(x+16)
y-8 = mx+16m
y = mx+16m+8
you have to calculate m, which can be possible if two coordinates are given otherwise it's the final possible answer...
