define "linear equation" and "function."
* * * * *
Suppose f is a mapping from one set of numbers (the "domain") to another (the "range"). The domain and range may be the same or different.
If, for each and every element in the domain, f assigns one and only one elemnt in the range, then f is a function.
For example, f might be "double the number and then add 23", or "square root the number and then divide by 7". In the second case, the domain cannot have any negative numbers in it (why?).
A linear equation is a function of the form y or f(x) = mx + c where m and c are constants and x and y are variables. The function f maps every value of x in the domain x onto the value y according to the rule: multiply by m and add c.
The equation is called linear because for any pair of values x1 and x2 and the corresponding values y1 and y2, the ratio (y2 - y1)/(x2 - x1) is the constant m.
An equation is the same as a function. Identifying a functional relationship from a graph is nearly impossible unless it is trivially simple like a linear relationship.
They are the same.
Yes.
The equations are equivalent.
No....not necessary
No a linear equation are not the same as a linear function. The linear function is written as Ax+By=C. The linear equation is f{x}=m+b.
No a linear equation are not the same as a linear function. The linear function is written as Ax+By=C. The linear equation is f{x}=m+b.
No. A function need not be linear. For example, y = sin(x) is a function of x but it is not a linear equation.
Yes, a vertical line is linear, but it is not a function, because every point on the line has the same x value.
No. A linear equation is just one type of function.If you graph a linear equation, you get a straight line.A "function" on the other hand can take on many different forms: a straight line, a wave line (the sine function), a parabola, etc.No. A linear equation is just one type of function.If you graph a linear equation, you get a straight line.A "function" on the other hand can take on many different forms: a straight line, a wave line (the sine function), a parabola, etc.No. A linear equation is just one type of function.If you graph a linear equation, you get a straight line.A "function" on the other hand can take on many different forms: a straight line, a wave line (the sine function), a parabola, etc.No. A linear equation is just one type of function.If you graph a linear equation, you get a straight line.A "function" on the other hand can take on many different forms: a straight line, a wave line (the sine function), a parabola, etc.

They are not. An inequality cannot, by definition, be the same as an equation.
They are the same.
Yes.
Yes.
Yes, they refer to the same thing.
The equations are equivalent.
