Answer 2

The value of x is 1.

Step-by-step explanation:

Given : The slope of the line joining two points (2,5) and (x,3) is 2.

To find : The value of x ?

Solution :

The slope formula of two point  $(x_1,y_1),(x_2,y_2)$ is given by,

$m=\frac{y_2-y_1}{x_2-x_1}$

Here, $(x_1,y_1)=(2,5)\ ,\ (x_2,y_2)=(x,3)$ and m=2

Substitute the value,

$2=\frac{3-5}{x-2}$

$2(x-2)=-2$

$2x-4=-2$

$2x=2$

$x=\frac{2}{2}$

$x=1$

Therefore, the value of x is 1.
