Answer:
<h2>B. y - 1 = -3(x - 9)</h2>
Step-by-step explanation:
The point-slope form of an equation of a line:

m - slope
(x₁, y₁) - point
The formula of a slope:

We have the points (9, 1) and (4, 16). Substitute:


Answer:
As in 4 hours , 20 men can cut 30 trees. So, in 1 hour , 20 men can cut 30 trees / 4. So, in 6 hours, 20 men can cut 30 * 6 trees / 4 = 45 trees.

and
, which expands to 
Answer:
-9x + 5
Step-by-step explanation:
Slope Intercept Form = y = mx + b
where x = slope and b = y intercept
We are told that the slope is -9 and the y intercept is at (0,5)
So x = -9 and b = 5
that being said we plug in the values into the equation
Therefore y = -9x + 5 is your answer
