D because each y value is obtained by multiplying x by -2
y = -2x which is direct variation.
Answer:
Literally any number larger than 17. Example: 18.
Since 4pi/3 = 3pi/3 + pi/3 = pi + pi/3, that means it goes past the angle of pi (the negative x-axis), and an additional pi/3 radians. So this gives you a diagonal line that passes through the origin, from the third quadrant through to the first quadrant, and makes an angle of 60 degrees with the negative x-axis.
