all right the question on this ladies and gentlemen asked me to to find the X and Y intercepts of the graph so to do that I'm going to give you guys a little bit of history of remember remembering x and y intercepts so first of all asking us to graph all right we're going to use the cartisian coordinate system okay where we have two axes right you have your y AIS your and your X axxis now remember we also start at the origin 0 0 okay now remember when we have a point that crosses the x axis a point that crosses at the x- axis is called the x intercept right you intercept the pass it intercepts the axis right now the main important thing that you guys need to know about that is when a point crosses the x intercept right remember we have these values 1 2 3 1 2 3 right then you go negative is down negative is to the left if I cross at x equals this value which is3 what is my yv value you guys really need to be looking up here and write it down what is my yv value over here3 no my x value you're right is neg3 but what's the Y value zero right so this at this point is my x intercept so if I'm asking you here's my equation which by the way is in standard form actually not really we could factor out a two but it's in the standard form format if I say tell me what the x intercept is you don't know what x is right but do we know what Y is y has to be what Z zero right because I said I don't know where the x- axis is but no matter what Y is going to be zero so what we write is I always like to write two forms I already say x intercept and I say y equals z then what do you think it' be for the Y intercept what do you think X is on this Y intercept Z so then I write Y intercept xal 0 so we're going to do the problem twice one for the x intercept one for the Y intercept because that's what I ask you to do right find the X and the Y intercept right Anna Anna could you please put that away so what does it mean when y equals z we're going to plug zero in for your variable y y equals zero because look it let's pretend here's my point right let's say I have a graph crosses it right there at that coordinate point right you had to go over one two three so you went over negative3 but then how high up and down did you go on the y axis you didn't go anywhere right so it's -3 comma 0 does that make sense okay now teachers pardon the interruption I do have some bus changes to announce today students who ride 6 ride 531 today it will be a late you use this to find the X where it crosses the two axes and then connect I'm gonna wait when he down I'm going explain it hold on hold on hold on ride df6 okay so not down here yet Cedric so ladies and gentlemen remember at each y intercept or x intercept the other value is equal to zero can we hold off ladies and gentlemen Catherine yes so now what we're going to do is plug zero in for x and solve what's 2 * Z zero so I'm left with 6 6x = 6 divide y always equals Zer for the X AIS or I'm sorry the x intercept whenever you want to find the x intercept y equals z well you're that's what we're trying to find that's the problems asking is find the x intercept now to find the Y intercept you plug xal 0 that's equal 0 so you have 2 y = 6 / 2 y = 3 now these coordinates remember I said this is the x intercept so how do you write that as a coordinate point remember every point on the graph has an X and a y coordinate right well your x coordinate is one the y-coordinate is zero here your Y intercept your x coordinate is zero your y coordinate is three so plot those two points 1 comma 0 is right here 0 comma 3 is right there you connect and then you solve you gra yes separ
