no, its rational
Proportional is when it is proportional.
Directly proportional relationship is F=ma, F is directly proportional to a. Inversely proportional relationship is v=r/t, v is inversely proportional to t.
Its orientation.
It is true in the case of inversely proportional relationship.
You cannot represent a proportional relationship using an equation.
A proportional relationship exists when two variables are related by a constant ratio. In the expression y-2.5x, there is no constant multiplier connecting y and x, indicating a non-proportional relationship. If the relationship were proportional, the expression would be in the form y = kx, where k is a constant.
If the ratio between each pair of values is the same then the relationship is proportional. If even one of the ratios is different then it is not proportional.
24/yx there isn't an = sign
If the graph is a straight line through the origin, sloping upwards to the right, then it is a proportional linear relationship.
they are equivalent
The two variables are in inverse proportion and, graphically, will form a hyperbola.
Do all linear graphs have proportional relationship
