Answer:

-3

Step-by-step explanation:

(

$(2,-5)=(x_1,y_1) \\ (4,-11)= (x_2,y_2) \\$

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

Plug in values into the given equation

$m = \frac{ - 11 - ( - 5))}{4 - 2} \\ \\ m = \frac{ - 11 + 5}{2} \\$

Simplify

$m = \frac{ - 6}{2} \\ m = - 3$

3x+4y+6z=15 Solve for x.

aalyn [17]

Answer:

Step-by-step explanation:

<h3>Question:-</h3>

To solve for x

<h3>Equation:-</h3>

3x + 4y + 6z = 15

<h3>Solution:-</h3>

=> 3x + 4y + 6z = 15

[On subtracting both sides with 4y]

=> 3x + 4y + 6z - 4y = 15 - 4y

[On Simplification]

=> 3x + 6z = 15 - 4y

[On subtracting both sides with 6z]

=> 3x + 6z - 6z = 15 - 4y - 6z

[On Simplification]

=> 3x = 15 - 4y - 6z

[On dividing both sides with 3]

$= > \frac{3x}{3} = \frac{15 - 4y - 6z}{3}$

[On Simplification]

$= > x = 5 - \frac{4}{3} y - 2z \: (ans)$
