How do you know a graph shows a proportional relationship?
A graph shows a proportional relationship if it is a straight line that passes through the origin (0,0). This indicates that as one variable increases, the other variable increases at a constant rate. Additionally, the ratio of the two variables remains constant throughout the graph. If the line is not straight or does not pass through the origin, the relationship is not proportional.
A straight line on a graph means there is a what relationship between the dependent variable and the independent variable?
Proportional. linear
What are the characteristics of inverse proportionality relationship?
If the product of two variables is equal to a constant, then they are inversely proportional. eg. If xy=c where c is a constant, then x and y are inversely proportional.
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 are characteristics of exponential growth?
The main characteristic is that the more it rises, the more quickly it rises. The slope is proportional to the height of the graph. So the growth quickly gets out of hand.
