A function whose graph forms a straight line?
A linear function.
How to scketch graphs of functions?
the domain value is the x coordinate, and the range is the y coordinate. after graphing, do the vertical-line-test to see if it is a function or not.
Is the y axis the vertical line when line graphing?
yes, and the x-axis is horizontal
Is graphing the function useful in helping to solve a practical problem?
yes
How do you find coordinates of a line from an equation without graphing?
By substitution
How do you figure out the equation of a table with a graphic calculator?
It depends on which calculator! If the data is linear, you can estimate the slope of the line and the y-intercept from graphing the data. By graphing the data, you will be able to tell if it forms a straight line or not.
What is a function that forms a line when graphed called?
It is a continuous function. If the line is a straight line, it is a linear function.
A function whose graph forms a straight line?
A linear function.

What is the difference between graphing a line and graphing an inequality?
when graphing a line you simply plot the points based on the ordered pairs and connect the dots; there you have a line. An inequality graph refers to the shaded region of the coordinate plane that does not coincide with the line, hence the term, inequality.
What is the most economic model?
line graphing
Why a constant function doesn't have an inverse function?
When graphing functions, an inverse function will be symmetric to the original function about the line y = x. Since a constant function is simply a straight, horizontal line, its inverse would be a straight, vertical line. However, a vertical line is not a function. Therefore, constant functions do not have inverse functions. Another way of figuring this question can be achieved using the horizontal line test. Look at your original function on a graph. If any horizontal line intersects the graph of the original function more than once, the original function does not have an inverse. The constant function is a horizontal line. Under the assumptions of the horizontal line test, a horizontal line infinitely will cross the original function. Thus, the constant function does not have an inverse function.
What is graphing method?
In systems of equations, the graphing method is solving x and y by graphing out the two equations. x and y being the coordinates of the two line's intersection.
How do you find the slope of a line without graphing?
guess it
How do you find a linear function?
By finding something who's behavior is represented by a linear function and graphing it.
What is a function that forms a line graphed?
Any function of the form f(x) = ax + b, or any relation of the form Ax + By = C.This is the function that forms a line graphed. The slope of line can be taken out as C/A. * * * * * The above answer assumes that a line MUST be a straight line! Since the graph is a line, the domain must be an interval in the Real numbers. The interval may be finite, or infinite in one or both directions. In order that the graph does not have breaks in it the function must be continuous. Any such function will do.
Is the y axis the vertical line when line graphing?
yes, and the x-axis is horizontal
