$\left(\frac{3}{7}x+9\right)-\left(\frac{2}{7}x-3\right)\\\\=\frac{3}{7}x+9-\frac{2}{7}x-(-3)\\\\=\frac{3}{7}x+9-\frac{2}{7}x+3\\\\=(\frac{3}{7}x-\frac{2}{7}x)+(9+3)\\\\=\frac{3-2}{7}x+12\\\\=\boxed{\frac{1}{7}x+12}$

HELP PLEASE! What is the slope of the line shown?

Alja [10]

Answer:

A. -4/11

Step-by-step explanation:

Slope formula: $\frac{y^2 - y^1}{x^2 - x^1 }$

Using the two points substitute the coordinates into this formula

6-2 = 4

4 - 7 = -11

Put 4 over -11 because it is the y value

$-\frac{4}{11}$
