Answer:

x = 0 1 -1 -2

y = -3 -4 -2 -1

Step-by-step explanation:

equation : 3y+9x = -9

when x = 1

3y+3x = -9

or, 3y + 3×1= -9

or, 3y+3=-9

or, 3y = -12

so, y = -4

Again

Let's suppose x as -1

3y+3x= -9

or, 3y+ 3×-1 = -9

or, 3y-3 = -9

or, 3y = -6

y = -2

Let's suppose x as -2 now,

3y+3x = -9

3y+3×-2 = -9

or, 3y-6 = -9

or, 3y = -3

so, y = -1

Determined to find the slope (1 7K), and (-3,5K)

Helga [31]

Answer: $\dfrac{K}{2}$ .

Step-by-step explanation:

As we know ,

The slope of a line that passes through $(x_1,y_1)$ and $(x_2,y_2)$ is given by :

$\dfrac{y_2-y_1}{x_2-x_1}$

The slope of a line that passes through (1 , 7K), and (-3,5K) =

$\dfrac{5K-7K}{-3-1}\\\\=\dfrac{-2K}{-4}\\\\=\dfrac{K}{2}$

Hence, the slope of the given line is $\dfrac{K}{2}$ .
