Solution to the 1st equation: x
3x-6y=-12
3(x-2y)=-12
x-2y=-4
→x=2y-4

Solution to the 1st equation: y
3x-6y=-12
3(x-2y)=-12
x-2y=-4
-2y=-4-x
→y=-4-x/2

Can someone tell me the slope ?

borishaifa [10]

Answer:

slope = 4

Step-by-step explanation:

We can find the slope of a line when knowing 2 points by using the slope formula, $\frac{y_2 - y_1}{x_2 - x_1}$ . $x_1$ and $y_1$ represent the x and y values of the first point, respectively. $x_2$ and $y_2$ represent the x and y values of the second point, respectively.

The two points we have are (2,8) and (0,0). So, in this case, $x_1$ = 2, $y_1$ = 8, $x_2$ = 0, and $y_2$ = 0. Let's substitute those values into the formula and solve to get the slope:

$m =$ $\frac{0-8}{0-2}$

$\frac{-8}{-2}$

$4$

So, the slope is 4.

If you mean you get them by diving them by 100 or something over 100(as in a fraction) that's the answer, I'm incredibly sorry if it is not what you meant!
