The easiest way to graph simple linear equations like this one is to remember this:
Only two points are required in order to graph a line.
Points are just (x,y) pairs.
To make the math easy, I just use 0 for one of the values and then solve for the remaining one.
In this case:
Setting x = 0, yields

Thus, .
So one point is (0,10)
Now use y = 0 and solve for x.

Thus
Another point on the line is (10,0)
Plot those two points and you have the graph.
As far as a y-intercept goes, all that means is "find the point where the line crosses the y axis". What do you know about the value of x for any point that is on the y axis? That's right, x is always 0. We have already found the point (0,10), so you already have the answer :)
