Given AP is 21 ,18,15,...
First term = 21
Common difference = 18-21 = -3
Let an = -81
We know that
an = a+(n-1)d
⇛21+(n-1)(-3) = -81
⇛ 21-3n+3 = -81
⇛24-3n = -81
⇛ 24+81 = 3n
⇛ 105= 3n
⇛ n = 105/3
⇛ n = 35
35th term of the AP is -81.

Slop: m=y2-y1/x2-x1
m=3-1/3-(-2)
m=2/5
Substitute (3,3) into the formula y=mx+b
3= 2/5•3+b
9/5=b
So y=2/5x+ 9/5
