Yes it can. A linear equation in the form of y=mx+b can always be graphed used the x and y intercepts.

Because it fits the data. That's an extremely vague answer, but it was an extremely vague question.

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.

Linear equations are used to find the value of missing numbers. They are also used to find the relation among the missing numbers. For example= x+3=4 x=4-3 x=1

in an equation like y=5x+3 the 3 would be the y-intercept

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.

You can't have a square root in a linear equation other than to express a constant. If it is used as such, it is represented the same way as in any other branch of mathematics.
