Given:

A line passes through the points (9,9) and
(x_2,-1).

The slope of the line is
(5)/(6).

To find:

The value of
x_2].

Solution:

Slope formula:


m=(y_2-y_1)/(x_2-x_1)

The line passes through the points (9,9) and
(x_2,-1). So, the slope of the line is:


m=(-1-9)/(x_2-9)


m=(-10)/(x_2-9)

It is given that the slope of the line is
(5)/(6).


(5)/(6)=(-10)/(x_2-9)


5(x_2-9)=-10(6)


5x_2-45=-60


5x_2=-60+45


5x_2=-15

Divide both sides by 5.


x_2=-(15)/(5)


x_2=-3

Therefore, the value of
x_2 is
-3.
