    ExamSolutions finds the y coordinate for the first example.

    How comes he did not do so in the second example?

    In the second one the line crosses the y axis at 0 so maybe that's it?

    The first example is the one under the  X^3 graph

    The second example is the one under the  -X^3 graph

    It doesn't matter whether you find where is crosses the x axis or the y axis first.

    In the second example it crosses at 0,0 so there is no y intercept to find
