Idk, pick one of them, thats ur best bet
This is in the third quadrant where the tangent of the angle is positive
tan pi/4 = 1 = y/-1 so y = -1
The required point is (-1,-1)
10/14 = 5/7
30/36 = 5/6
answer
not proportional
For this problem, you would have to use a system of equations. Hope this helps!
