Question

I need help with this question!!!! Given directed line segment QS, find the coordinates of R such that the ratio of QR to RS is 3:5. Plot point R.

Answer 1

Answer:

• R(2, -2)

Step-by-step explanation:

Coordinates of Q and S are:

• Q(8, -5), S(-8, 3)

We need to find the coordinates of R such that:

• QR : RS = 3 : 5

Let R has coordinates (x, y):

• x = 8 + 3/8(-8 - 8) = 8 - 6 = 2
• y = -5 + 3/8(3 + 5) = -5 + 3 = -2

The point is R(2, -2)
