Vector u has its initial point at (21, 12) and its terminal point at (19,-8). Vector v has a direction opposite that of u, whose magnitude is five times
the magnitude of v. Which is the correct form of vector v expressed as a linear combination of the unit vectors i and j?
A.
v= -101 + 4j
B.
v=-0,41 - 4j
C.
v=0,41 +4j
D.
v = 15i + 100)

C. v= 0.4i+4j

Step-by-step explanation:

I just took the test and that was the right answer

y=mx+b

step-by-step explanation:

m slope, b y-intercept

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
