Answer:

Step-by-step explanation:

The formula to find the x coordinate is

[tex]x=\frac{bx_1+ax_2}{a+b}[/tex] 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:

[tex]x=\frac{5(-6)+2(8)}{2+5}=\frac{-30+16}{7}=\frac{-14}{7}=-2[/tex]

Your choice is B
