We will put ur equation in y = mx + b form, and the slope will be in the m position.

14x + 7y = -9
7y = -14x - 9
y = (-14/7)x - 9/7
y = -2x - 9/7

y = mx + b
y = -2x + (-9/7)....as u can see, the -2 is in the m position and is therefore the slope.

The sum of two numbers is 14. When one number is added to twice the other number, the result is 25. Find the numbers

ELEN [110]

Let x and y be the two numbers. We have:

$\begin{cases}x+y=14\\x+2y=25\end{cases}$

Subtract the first equation from the second to get

$y=11$

And deduce

$x+11=14 \iff x=3$

The two numbers are 3 and 11.
