Vector addition and subtraction!:)

Vectors are the same as slope!
Vector addition: u + v. ux+vx, uy+vy
Vector subtration: u - v. ux-vx, uy-vy
To find a vector from 2 points: p2-p1

Examples!
Using u<3,7> v<6,9>.
1.) find u+v
3+6,7+9=<9,16>

2.) find u-v
3-6,7-9=<-3,-2>

3.) find the vector from (-5,6) & (4,-2)
4--5,-2-6=<9,-8>
