The required value ofu+v=-2,4andu-v=4,-8.

Step by step solution

01

Step 1. Given information. 

We have given vectoru=1,-2andv=-3,6

02

Step 2. Find the values of u+v and u-v.

u+v=x1+x2,y1+y2=1+-3,-2+6=1-3,-2+6=-2,4

and

u-v=x1-x2,y1-y2=1--3,-2-6=1+3,-2-6=4,-8

03

Step 3. Sketch u , v u+v and u-v

The graph of vector u+v.

The graph of vector u-v.
