Use distrubutive property <em>a(b + c) = ab + ac</em>

6(5r - 4) - 2(r - 7s - 3)

= (6)(5r) + (6)(-4) + (-2)(r) + (-2)(-7s) + (-2)(-3)

= 30r - 24 - 2r + 14s + 6

= (30r - 2r) + 14s + (-24 + 6)

Determined to find the slope<br>(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 $\dfrac{K}{2}$ .
