<u>Solution:</u>
- 3⁸¹ = 3⁹ ⁺ ⁹ ⁺ ⁹ ⁺ ⁹ ⁺ ⁹ ⁺ ⁹ ⁺ ⁹ ⁺ ⁹ ⁺ ⁹ ⁺ ⁹
- 3⁸¹ = 3⁹ x 3⁹ x 3⁹ x 3⁹ x 3⁹ x 3⁹ x 3⁹ x 3⁹ x 3⁹
- 3⁹ = 19683 <u>[Using Calculator]</u>
This means that the Unit digit of 19683 is 3. For each number, multiply the unit's digit of 3⁹.
- 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3
- => 19683
- => <u>Unit digit of 3⁸¹ = 3</u>

The general equation of a line is y = mx +b.
m is equal to the slope, so for this problem it is m = -3
b is equal to the y-intercept (the y-point when x = 0) so according to this since it passes through (0, -2), x=0 at y = -2
The equation of the line is: y = -3x - 2
