Question

What is the slope of the line described by the equation?
y- 4 = -9(x-8)

Answer 1

the slope is -9.
y-y1=m(x-x1) point-slope form
m being the slope

Answer 2

The slope is -9

Explanation:

Your slope will always be mx in y = mx + b

Step 1: Distribute

y - 4 = -9x + 72

Step 2: Isolate y

y = -9x + 76

Step 3: Look for mx

And you have your final answer.
