An equation is a statement that two things are equal. A function is a rule or process that gives you a value if you give it something in its domain (the set of things on which it is defined) as an argument. Functions on numbers that are defined by a rule can usually be expressed by an equation. A linear function is one that can be defined by a linear equation.
usually bank accountants ..... they use it to find out things like interest ans S.P , C.P etc..
On all of the graphing calculators, they have the graphing things on it. First to make a graph, you need an equation. when you have the equation ready, you just press the button on the top left (for the most calculaters), the "y=" button. Then you will get a lot of empty lines for you to put the equations on. After you type all the equations, you will have to press the "graph button on the top right. then you will get a graph.
It's a simple linear equation in two unknowns.If you want to know what value of 'x' or 'y' makes it true, you'll need another equation.You always need as many equations as there are unknowns.From the single equation given in the question, we only know these two things:-- whatever 'x' is, 'y' is [double it] less than 1/2-- whatever 'y' is, 'x' is [half of it] less than 1/4
You can measure things with a linear scale. Practically impossible with a non-linear scale.
