Answer: y = - 4x + 2
Explanation:
The graph shows a linear function, which is a first degree polynomial, whose form is ax + b.
The rule or fucntion is f(x) = y = ax + b. This form is called the slope-intercept form, because the coefficient a is the slope of the line and b is the y-intercept.
The graph permits you to calculate both parameters.
1) The slope, a is defined in this way:
- a = rise / run = [change in y] / [change in x] = [y₂ -y₁] / [x₂ - x₁]
- you can use the points (0, - 2) and (-1,2):
⇒ a = [ 2 - (-2) ] / [ -1 - 0 ] = 4 / (-1) = - 4
2) b, the y-intercept, is the value of the function, y, when x = 0. In the graph you can see that this is - 2. b = - 2.
3) Substituting the values of a and b in the form y = ax + b, you the rule:

Answer:
$81.70
Step-by-step explanation:
15.95 x 4 = 63.80
8.95 x 2 = 17.90
63.80 + 17.90
<h2>
Answer:</h2>
720 pounds
<h2>
Step-by-step explanation:</h2>
Initially, we have that the amount of algae in the pond is 
. Every four hours the amount of algae doubles. If we called 
the time and 
the amount of algae, we have that:
Finally, <em>after 12 hours the amount of algae in the pond is 720 pounds</em>
