These are (hopefully) the last ones I need help with. I have over 100 questions and I'm just having a difficult time. Sorry.

point P = (-7, 3)
point Q = (2, 1)
| _____Ratio_____ | Coordinates | |
| 2:7 | x-coordinate = −7+22+7⋅|−7−2|=−7+29⋅9=−7+2=−5 y-coordinate = 3−22+7⋅|3−1|=3−29⋅2=3−49=239 |

| 3:5 | x-coordinate = −7+33+5⋅|−7−2|=−7+38⋅9=−7+278=−298 y-coordinate = 3−33+5⋅|3−1|=3−38⋅2=3−34=94 |
It looks like you have found the same coordinates out to the side? 
+130474 First one
SU = LN = sqrt [ (8 - 0)^2 + (6 - 0)^2 ] = sqrt [ 64 + 36 ] = sqrt [ 100 ] = 10
And
TV = MP = sqrt [ (6 - 2)^2 + ( 4 - 2)^2 ] = sqrt [ 4^2 + 2^2 ] = sqrt [20 ] = 2sqrt ( 5)
"D" would be correct except that I think the answer for TV is incorrect
