The y-intercept of a desk is the worth of y when x is the same as 0. It’s the level the place the road represented by the desk crosses the y-axis. To search out the y-intercept of a desk, merely take a look at the row the place x is the same as 0 and discover the corresponding y-value.
The y-intercept is necessary as a result of it tells you the preliminary worth of y earlier than any change in x happens. This may be helpful for understanding the connection between x and y, and for making predictions about future values of y.
