Answer:

Step-by-step explanation:

A = p(1+r/n)nt

A = final amount

p = principal = 2000

r = interest rate = 0.024

n = # times compounded pet year = 12

t = time in years = 7

A = 2000(1+.024/2)12(7)

A = 2000(1.012)^84

The **value** of r in the given coordinates with their slope is; r = 7

**How to find the Slope of a Line?**

The** formula for slope** of a line passing through 2 points is;

m = (y2 - y1)/(x2 - x1)

We are given the** coordinates** as;

(1,-10) and (r,2)

The **slope** of the line passing through this **coordinates **is 2. Thus;

(2 + 10)/(r - 1) = 2

12 = 2r - 2

2r = 14

r = 14/2

r = 7
