Enable Editing Let's see how we can modify the tail-to-end method of addition to apply to vector subtraction. 9. Use component-wise subtraction to find (-7, 3) - (2, -8). 10. Draw the vectors (-7, 3) - (2. -8) tail-to-end. Describe a modified tail-to-end method that will make the resultant vector equal to your answer from #10. 11. How is subtracting vectors similar to the common "add the opposite" method of subtracting integers? 12. What is the advantage of presenting this subtraction problem in component form rather than direction-magnitude form? Now let's look at scalar multiplication in each form. 13. From Hogwarts, Harry walks three blocks East and two blocks North then rests. He repeats this four times total. Describe how Ron can walk to Harry's ending position from Hogwarts without stopping. 14. From Hogwarts, Hedwig flies four miles at a direction of 60 then rests. He repeats this four times total. Describe how Errol can fly to Hedwig's ending position from Hogwarts. FOCUS wFrom Hogwarts, Harry walks three blocks East and two blocks North then rests. He repeats this four times total.

Is the same true for scalar multiplication? Explain your answer. Practice Problems: Focus X FS FIO
