If the vectors point towards the same direction, the magnitude of the vector quantities are added as in, C = A + B. If they point towards opposite direction, the magnitudes are subtracted giving a resultant vector equal to C = A - B.
Step-by-step explanation:
The graph of a proportional relationship is a line through the origin. When ratios between quantities are not constant, a relationship may be linear but not proportional and the graph does not pass through the origin. Example : ... Explain why the relationship between number of tickets and total cost is not proportional.
So if it does not pass through the the origin, it’s not proportional.
