It is an expression, not an equation and so cannot be proportional nor non-proportional.
how to tell if a table s proportional or non proportional
Quota Share is proportional treaty.
They aren't.
If it is a 2-dimensional figure then it is proportional.
Any two non-zero quantities are always proportional. If the two quantities are X and Y, they are proportional to X/Y.
If two quantities are proportional, then they have a constant ratio.If the ratio is not constant, the two quantities are said to be non-proportional.Proportional will always go through the origin on a graph. (0,0)Graph will always be a straight line.Non-proportional line does not go through the origin.
If the graph is a straight line through the origin, sloping upwards to the right, then it is a proportional linear relationship.
Linear system has a proportional slope, which gives the system a straight line. And, a non-linear system has a non-proportional slope, which is represented by a non-straight line (usually a curved one). Feel free to edit if you think this is not to the point.
If you mean: y=7x -3 then it is a proportional relationship of a straight line equation.
