Question

determine x so that 2 is the slope of the line passing through A(2,4)& B (x,-2)​

Answer 1

Answer:

x=-1

Step-by-step explanation:

slope of AB is (-2-4)/(x-2) which is equal to 2

so solving above equation

-6/(x-2)=2

-3=x-2

x=-1

Answer 2

The value of x is -1.

Step-by-step explanation:

To find : Determine x so that 2 is the slope of the line passing through A(2,4) and B (x,-2)​ ?

Solution :

The slope form of line passing through two point is given by,

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

Here, $(x_1,y_1)=(2,4)\text{ and }(x_2,y_2)=(x,-2)$

Slope is m=2.

Substitute all values in the formula,

$2=\frac{-2-4}{x-2}$

$2x-4=-6$

$2x=-2$

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

$x=-1$

Therefore, the value of x is -1.
