Determine the intercepts of the line.

The y-intercept is where the line intercepts the y-axis, or the vertical axis

In this case, the y-intercept is

(0, 0.4)

The x-intercept is where the line intercepts the x-axis, or the horizontal axis.

In this case, the x-intercept is:

(0.3, 0)

Hope this helps :)
