Best ResponseYou've already chosen the best response.1linear function mean "line" and a line means the slope between any two points is the same in other words, change in y divided by change in x is the same for any pair of points. one way to test if the slope is the same is notice: when x goes up by 1 step, what does y do? for example from (3,3) to (2, 0) the x goes up (from 3 to 2) y goes up by 3 (from 3 to 0) now check the next points. Does y go up by 3 ? if so you have a line.
