Line AB contains points A (−2, 6) and B (4, 5). The slope of line AB is −6 negative 1 over 6 1 over 6 6

kolezko [41]

To work out the slope of a line, you have to divide the difference in y by the difference in x

The difference in y = 5-6 = -1
The difference in x = 4--2 = 6

Answer:

The average rate of change is 1.275

Step-by-step explanation:

The average rate of change of f(x) from x=a to x=b is given by:

$\frac{f(b)-f(a)}{b-a}$

The money Terry invested is modeled by the function $f(x)=0.01(2)^x$ where x represents number of days.

The average rate of change from day 2 to day 10 is given by:

$\frac{f(10)-f(2)}{10-2}$

$f(10)=0.01(2)^{10}=10.24$

$f(2)=0.01(2)^{2}=0.04$

The average rate of change becomes:

$\frac{10.24-0.04}{8}$

$=\frac{10.2}{8}=1.275$
