Use the distance formula. The change in the x-coordinate is 6 The change in the y-coordinate is -2 Using the Pythagorean Theorem. a² + b² = c² 6² + (-2)² = c² 36 + 4 = c² c² = 40 c = √40 c = √4√10 c = 2√10 Answer: a. ||v|| = 2√10

Magnitude = sqrt( (1-7)^2 +(3-1)^2) = sqrt(36+4) = sqrt(40)= sqrt(10)sqrt(4) = sqrt(10)*2 = 2 sqrt(10)

v = (7 - 1, 1 - 3) = (6, -2)

Use the distance formula √(36+4) = √40 = 2√10
