The given end points of the line of the given graph are J(-6,-2) and K( 8,-9).

We need to find the coordinate of x that divide the line segment from J to K in 2:5 ratio.

We are given formula also.

$x=\left((m)/(m+n)\right)\left(x_2-x_1\right)+x_1$

We have m = 2, n= 5, x1 = -6 and x2 = 8.

Plugging those values of m, n, x1 and x2 in above formula, we get

$x=\left((2)/(2+5)\right)\left(8-\left(-6\right)\right)+\left(-6\right)$

$=(2)/(7)\left(8+6\right)-6$

$=(2\cdot \:14)/(7)-6$

=4-6

x=-2
