the y-axis is up and down, the points on the graph aren't exact so you have to approximate but the first point sits at roughly (0.1, -1), the second number "-1" is the y-variable so that is the first intercept
the second points sit at roughly (1.9, 4) so the second y-intercept is 4
I recommend using desmos graphing calculator during this course, it's a lifesaver.
