If y varies directly as x, then the graph of y against x must be a straight line through the origin.

However, if y varies directly as the square of x, for example, then the graph of y against the square of x will be the straight line through the origin - not y against x.

In a table if the ratios weren't equivalent would it still be direct variation?

No; each ratio has to be the same for a direct variation.

The best graph for the purpose of comparing raw numbers between different qualitative categories would be a bar graph or some variation thereof.

What is a direct variation?

A direct variation is when the value of K in multiple proportions is all divisible by the same number for example: XY=(1)(10) K=10 XY=(2)(20) K=40 XY=(3)(30) K=90 XY=(4)(40) K=160 In this situation the constant (K) of each proportion is divisible by 10 making the multiple equations a direct variation.

What does make a key in science mean?

when you draw a graph a key helps identify what each line or collum stands for. colorcoding each line would halp in making a key.


Is 5x plus 3 equals 8y plus 3 a direct variation?

Oh, dude, direct variation is when two variables change in the same way. In this case, 5x + 3 = 8y + 3, so technically they are changing in the same way by adding 3 to both sides. So, yeah, I guess you could say it's a direct variation, but like, who really cares, right?


What does variation mean in math terms?

There are different types of variation in math - direct variation, inverse variation, and joint variation for a start. Direct variation is just simply that x and y vary directly. What this means is that they do the same thing - as x increases so does y, or as x decreases so does the value of y. In general the formula for direct variation is y=kx where k is the constant of variation. (For example we could have a direct variation equation such as y=2x. The constant of variation is 2, which just means that as x increases, y doubles that amount and thus also increases) Inverse variation is when x and y do the opposite of each other. So as x increases, y decreases or as x decreases the value of y increases. One fun example of where this happens in real life is with Ramen Noodles - the less money people make the more Ramen Noodles they buy. We would say that people's income and the amount of Ramen Noodles they buy vary inversely. In general the formula for inverse variation is y = k/x where again k is the constant of variation. Joint variation is when you have three variables that are related. The general formula for joint variation is y=kxz where z is just a third variable and k is still the constant of variation.


What is the cluster graph?

A cluster graph is a type of graph in which the vertices can be grouped into clusters or communities based on their connections within the graph. It is used to study the structure of complex networks and identify groups of vertices that are more densely connected to each other than to the rest of the network. Cluster graphs help in visualizing and analyzing the natural communities that exist within a network.


How is a direct variation a function?

A direct variation between two variables, X and Y, may be expressed in the form Y = c*X where c is some known, constant. This is a mapping from the set of values of X to the set of values of Y such that for each value of X there is only one value of Y - which is c*X. Such a relationship is a function.
