How do you know that an equation is proportional just by looking at it?
If each side of the equation is a fraction, then it is a proportion.
What are some examples of a proportional relationship?
some people being ugly and weird just kidding I'm only a third grader how should I know
How do you know if a fraction is proportional?
All fractions are proportional to some other fraction.
Explain how you know that y must decrease when x decreases?
First you have to tell me what equation you are using as the basis of this relationship between x and y.
How do you know is an equation is linear?
You know if an equation is linear if it is a straight line. You can also know if the equation is y = mx + b where there are no absolute values nor exponents.
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.
How do you know that an equation is proportional just by looking at it?
If each side of the equation is a fraction, then it is a proportion.
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 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.
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.
How do you know the relationship between x and y is proportional?
The answer depends on how the information is presented. If in the form of a graph, it must be a straight line through the origin. If in the form of an equation, it must be of the form y = cx.
What is an equation that shows the relationship among certain quantities?
Formula
What are the Importance of stoichiometry in chemical reactions?
stoichiometry is very important in chemical equations because it tells you the relationship between substances in the same chemical equation. If you know the properties and relationship of one substance in the equation, you can calculate the relationships between all the substances in the equation.
How do you find constant of proportionality?
You need to know the basic relationship between the variables: whether they are directly of inversely proportional to each other - or to a power of the other. Also, you need one scenario for which you know the values of both variables.So suppose you have 2 variables A and B and that A is directly proportional to the xth power of B where x is a known non-zero number. [If the relationship is inverse, then x will be negative.]Then A varies as B^x or A = k*B^xThe nature of the relationship gives you the value of x, and the given scenario gives you A and B. Therefore, in the equation A = k*B^x, the only unknown is k and so you can determine its value.
If x equals 1 3 when y equals 162 ο¬nd x when y equals 3?
You need to know what is the relationship between x and y. Are they proportional? Inversely proportional? Several other options also exist.
