The x and yintercepts are where the graph of a line crosses the x and yaxes. When given a graph, identify the point where the line crosses the xaxis. The coordinates of that point is the xintercept. Identify the point where the line crosses the yaxis. The coordinates of that point is the yintercept.
Finding x and y intercepts are the kind of problem it takes you longer to read than it takes you to do, and here is what I mean.
If you’re given a graph like this, all you want to look for to find the yintercept is the place where the line crosses the yaxis. Remember the y axis is the vertical one. So if you look at your graph, here is the place where the y crosses, excuse me the graph crosses the yaxis, it’s at then point 0 for x, 4 for y. That’s my y intercept, so that’s it.
To find the x intercept, I’m looking at the x axis, it crosses right here at 3 for x, zero for y. The only trick that a lot of students make is they forget that these represent as two separate points, so when you’re answering these problems, make sure you write it as two different points, x intercept is 3, 0, the y intercept is (0,4) not (3,4). That’s a really common mistake.
Keep in mind these are two separate points, so you’re going to have two separate answers. Again these are some of my favorite types of Math problems because you can do it just like that.

Your tutorials are good and you have a personality as well. I hope you have more advanced college level stuff, because I like the way you teach.”
Thanks alot for such great lectures... I never found learning this easier ever before... keep up the great work.... :)”
You seem so kind, it's awesome. Easier to learn from people who seem to be rooting for ya!' thanks”
