How to Calculate Y-Intercept in Excel. The y-intercept is the point at which a linear equation crosses the y-axis on the x=0 plot point.

Let's look at the idea of what an x and y intercept are. Basically, an x intercept is where it intercepts the x axis, and the y intercept is where it intercepts the y axis.

The plot function creates a 2D plot with the slope-intercept form of the equation, and the (x,-10,10) part specifies the range of the graph, between the x values of -10 and 10.
