How do we know when an equation represents a proportional relationship?
If it passes through the origin
What is directly and inversely proportional relationship?
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.
What is an example of proportional relationship?
they are equivalent
Do linear graphs represent proportional relationships?
Do all linear graphs have proportional relationship
Why each relationship is not proportional?
Some are, some are not.
Does the graph represent a proportional or non-proportional liner relationship How do you know?
If the graph is a straight line through the origin, sloping upwards to the right, then it is a proportional linear relationship.
How do we know when an equation represents a proportional relationship?
If it passes through the origin
How is a proportional and non-proportional relationship different?
Proportional is when it is proportional.
How do you know if a graph is proportional?
It is a graph of a proportional relationship if it is either: a straight lie through the origin, ora rectangular hyperbola.
What is directly and inversely proportional relationship?
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.
How can you represent a proportional relationship using an equation?
You cannot represent a proportional relationship using an equation.
Is it true that the graph of a proportional relationship does not include the origin?
It is true in the case of inversely proportional relationship.
How can you know if a graph represents a proportional relationship?
It is a relationship of direct proportion if and only if the graph is a straight line which passes through the origin. It is an inverse proportional relationship if the graph is a rectangular hyperbola. A typical example of an inverse proportions is the relationship between speed and the time taken for a journey.
Is y-2.5x a proportional relationship or no?
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.
How can you use a table to decide if a relationship is proportional?
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.
How do you figure figure how do you know if it is a proportinal relationship?
Suppose the two variables are X and Y. If, for any observation, X/Y remains the same, the relationship is proportional.
What is an example of proportional relationship?
