The terminal side of angle θ in standard position lies o the line 3a - b = 0 and sinθ < 0. What are the exact values of these trig functions?

No further details.

What do you mean "the line 3a - b =0"
 
If you draw the terminal side (which must be in third or fourth quadrant), what are the coordinates of the endpoint of the terminal side?

sines are negative in quadrants 3 and 4


if a = altitude and b= base

then the line 3a -b= 0 is 3a=b which goes through the origin

with angle = arctan(-1/3) base is 3 times as long as the absolute value of the height


coordinates of the terminal point are (b, -3a)
