Any time a line goes through a point with 0 as the x, the y would be the y-intercept
Your line goes through (0,2) so the y-int = 2
y = mx + 2
now solve for the slope and plug that into m
slope can be found by measuring the change in y over the change in x.
(2-2)/(5-0) = 0/5 = 0
So, the slope is zero.
y = 2 (This is our equation and the line is horizontal)

A lot of mine get frivolous down-votes. How about yours?

Gregg,
A lot of mine do too, especially in the last several weeks. A few other tutors have expressed similar concerns, and some of us sent suggestions to WyzAnt to modify the voting system, such as requiring either an uploaded comment or an alternative solution, before a down-vote is recorded. The proliferation of frivolous down-votes is a growing problem. I think that as more of us express our concerns to WyzAnt, the voting system may be changed. In the meantime, all we can do is continue to post good solutions.
