Answers:

Problem 7) Decay

Problem 8) Growth

Problem 9) Growth

==========================================

Explanation:

The base of the exponent will tell us if we have growth or decay.

In general, we have an equation in the form y = a*b^x with b as the base of the exponent

We can have b = 1+r where r is the growth rate. If r is negative, then that growth is really decay (or the amount is shrinking)

For problem 7, the base is 0.04 so 1+r = 0.04 leads to r = -0.96; so the amount is shrinking or decaying by 96% each time x increases by 1.

In problem 8, we have growth because 1.4 = 1+0.40 = 1+r so r = 0.40 = 40% growth

Finally, in problem 9, we can break up the base 6 into 6 = 1+5.0 = 1+r meaning r = 5.0 = 500% growth

What is the slope of a line that passes through the points (-5,-3) and (9,-6)
kipiarov [429]
To find the slope given two points, you need to subtract the two y values over the two x values
(-5,-3)  (9,-6)
-5 will be x1, and -3 will be y1. 9 will be x2, and -6 will be y2. You then need to put the numbers in the correct place in the equation.
y2-y1      -6-(-3)     -9
-------- =   -------- =  ----
x2-x1       9-(-5)     14
Now that we have the slope (-9/14) you can use one of the coordinates to find the value of b.
Let's use (9,-6).
-6=-9/14(9)+b
-6=-81/14+b
+81/14
b=-3/14
Your final equation is y=-9/15x-3/14
