Point P is located at (-2, 7), and point R is located at (1, 0). find the y value for the point Q that is located 2/3 the distan
ce from point P to point R.
a. 4.9
b. 4.7
c. 2.5
d. 2.3
1 answer:
Just did this one.
Answer: 7/3 or about 2.3, choice (d).
Step-by-step explanation:
R-P= (3,-7). the displacement vector.
P+x(R-P) moves to x times distance between
P+(R-P) = R moves to 100% of the distance.
Q = P+2/3(R-P)
= (-2,7)+2/3(3,-7)
= (-2,7)+(2,-14/3)
= (0,7-14/3)
= (0,7/3)
= (0,2.3333...)
