Answer:
The rate of change is -2
Step-by-step explanation:
f(b)-f(a) 12-2 10
---------- = ------------ = -------- = -2
b-a 1-6 -5
5. m=3 because 6/2 is the slope. b= 1
6. m= -4 because -20/5 is the slope. b= 140
Answer:
D.
x = 3, y = -7
Step-by-step explanation:
So this is going to be a linear equation, you can tell by seeing the growth being the same between days 15 and 20 & 33 and 38. We will be using the

format, where m = slope and b = y-intercept.
The equation to solve for the slope is

. You can use any two ordered pairs on this list. I'll be using 15 and 20.

45 is the slope.
To solve for the y-intercept, plug in 45 in the m variable and any ordered pair into the x and y variable spot. For this, I'll be using (15, 815)

Now putting the equation together (

) we can plug in 26 into the x variable and solve.
In short, the answer is B. 1,310 feet.
