Answer 2

I assume you want the slope of the given line. Here are 2 ways to find it:

(1)

The point slope form of the equation of a line is

y - y₁ = m(x - x₁)

Note the given equation is in point slope form. Compare and see that

m = 2/3

(2)

Get the equation in the form

y = mx + b

y = (2/3)x - (2/3)(9) - 1

y = (2/3)x - 7

m = 2/3
