Question

Of

What is the x-coordinate of the point that divides the
directed line segment from J to k into a ratio of 2:5?
A. -4
B. -2
C.2
D.4

Answer 1

Explanation:

The formula to find the x coordinate is

`x=(bx_1+ax_2)/(a+b)` where x1 and x2 come from the coordinates of J and K, and a = 2 (from the ratio) and b = 5 (from the ratio). Filling in:

`x=(5(-6)+2(8))/(2+5)=(-30+16)/(7)=(-14)/(7)=-2`

Your choice is B
