Question 5 options: The rule (x, y)→(x+2, y−4)(x, y)→(x+2, y−4) represents a translation 2 units___________________ and 4 units
PtichkaEL [24]
The hint is given by the translation with respect to the y-axis. Since the translated y-coordinate is subtracted with 4, it is translated 4 units downwards. Since the x-coordinate is added with 2, that means that<em> the original coordinate is moved 2 units to the right.</em>

Answer:

||u|| = sqrt((0 + 3)^2 + (4 + 2)^2) = 6.71

||v|| = sqrt((3 + 0)^2 + (3 + 2)^2) = 5.83

slope of u = 4/2 = 2

slope of v = 5/3

=> Option D is correct
