What is the linear equation used to represent a proportion?
y = cx where c is the constant of proportionality.
What is dilation in mathematics?
I t is a form of transformation in which all the linear dimensions of a shape are increased by the same proportion.
What happens to the volume when you enlarge a 3d object?
The volume increase - ib proportion to the cube of the linear increase.
Is y equals 2x a linear function?
Yes it is. the two numbers will always have the same proportion to each other.
What are all the proportion lines called?
In linear perspective there is a horizon line and a vanishing point to which all non horizontal lines lead to. There are also vertical lines. Proportion lines are simply a starting point for an artist to determine the correct proportions of the portrait or picture.

When cost relationships are linear total variable prime costs will vary in proportion to changes in?
Volume of Production

The volume increase - ib proportion to the cube of the linear increase.
When the ratio of two variables is constant their relationship can be describe as?
Direct proportion, linear, first-order... all of these are valid answers, depending on the particular field you're talking about.
Is y equals 2x a linear function?
Yes it is. the two numbers will always have the same proportion to each other.
What is proportional linear relationship in math?
The graph of a linear proportion will be a straight line passing through the origin. The equation will have the form y = mx, also written as y = kx.
What is a non example of a proportion?
A linear relationship whose graph does not pass through the origin: for example, the relation between temperatures on the Celsius and Fahrenheit scales.
Is a quadratic function proportional?
I'd say no. A quadratic is not linear. It's slope is constantly changing, so there is not one proportion which can be used to predict future values.

Does a graph showing direct proportion always have to be a straight line?
Assuming both the scales on the graph are linear (that is to say that the numbers go up evenly) then YES, a graph which shows direct proportion must be a straight line. It must also pass through the origin (0,0). A straight line which does not pass through the origin is NOT showing direct proportion. Duncan
What are the 4 types of proportion?
direct proportion indirect proportion additive proportion partitive proportion
