What can a triangle represent in a periodic equation?
In a periodic equation a triangle can be used to represent the given change of something.
How do you know if numbers show linear relationship?
A linear equation looks like any other equation. It is made up of two expressions set equal to each other. A linear equation is special because: It has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction. When you find pairs of values that make the linear equation true and plot those pairs on a coordinate grid, all of the points for any one equation lie on the same line. Linear equations graph as straight lines.
A linear equation cannot always be graphed by using intercepts alone?
Yes it can. A linear equation in the form of y=mx+b can always be graphed used the x and y intercepts.
Why linear equation is used?
Because it fits the data. That's an extremely vague answer, but it was an extremely vague question.
What is a linear equation or slope used everyday and in business?
A linear equation may be used to convert a unit price to a price for the quantity that you want. For example, if one bottle of drink costs C units then (at that same price) 5 bottles will cost 5*C units. It is used in the same way by businesses.
