Let u = 2i + 3j, v=-i, and w = 5i – 6j. What is the magnitude of 2(u – y + w)? O 10.0
O 13.4
O 17.1
O 21.6

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
