Q21
Its about finding the equation of  a straight line which is always y=mx+c
First find the gradient
Using 1,-2 and 4,3
y2-y1/ x2-x1
m= 3-(-2)/4-1
m =3+2/3
m=5/3

Then, substitue m=5/3 in the equation y=mx+c

y=mx+c (using 1,-2)
-2 = 5/3 X 1 + c
-2 = 5/3 + c
c = 11/3

Then, substitute m and c in y = mx+c
so the equation of the line is y=5/3x + 11/3

(By the way i hope this is the question you were after:P)

use compound interest formula

A= P(1+R/100)n

 = 2000(1+4.9/100)3
 =2308.64
             2308.64-2300= 8.64
