You can get a visual representation of the line by plugging in values for xcoordinates and solving for the ycoordinate.

Best ResponseYou've already chosen the best response.0A linear function is an equation of a line or parabola that passes the vertical line test, as my 8th grade Algebra 2 teacher is always reminding my class. The vertical line test is to see if the line passes the function... No x value has more than one y value. (No cheating). It's not just a whole bunch of points, they are organized on a line. :)
