Question 330407: the question was find the slope of the line passing through each pair of points, if possble. I got both questions wrong on my test. It was P(3,7);Q(6,16) and the other was P(5,17);Q(17,17) the sample they gave for these did not prepare me for that test.

I'll do the first one to get you started


Let's find the slope of the line passing through the points and


Note: is the first point . So this means that x%5B1%5D=3 and y%5B1%5D=7.
Also, is the second point . So this means that x%5B2%5D=6 and y%5B2%5D=16.


m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29 Start with the slope formula.


m=%2816-7%29%2F%286-3%29 Plug in y%5B2%5D=16, y%5B1%5D=7, x%5B2%5D=6, and x%5B1%5D=3


m=%289%29%2F%286-3%29 Subtract 7 from 16 to get 9


m=%289%29%2F%283%29 Subtract 3 from 6 to get 3


m=3 Reduce


So the slope of the line that goes through the points and is m=3

P(3,7);Q(6,16)
slope of a line m = y2-y1/ x2-x1 for points (x1,y1) & (x2,y2)
use the formula for the above points
16-7 / 6-3
=9/3
=3
and the other was P(5,17);Q(17,17)
17-17/ 17-5
=0
