In order to graph linear equations by finding intercepts, we must remember what an x and y intercept are. So remember that in an x-intercept it’s the y that equals zero, and for the y-intercept it’s ...

The y-intercept is the point at which a linear equation crosses the y-axis on the x=0 plot point. The equation to determine both the slope and the y-intercept of a line is y=mx+b.

So the y intercept, notice, at any point along this y axis here, that all that is going to be is a zero for our x's, and of course it can be any y possible. So, now let’s look at say if we had a ...
