    To find y - intercept set x = 0 and solve for y, for the graph it's where the function crosses the y - axis.

    y=mx+b, b is the y - intercept here

    \[f(x)=4x+5\] \[0=4(0)+5.\] \[y=9\]

    Set x = 0 and solve for y, y = 4(0)+5 -> y=5 or just read from y = mx+b

    Ah! You're right, my mistake... I added 4 to the 0. 4(0) = 0. So yes, y = 5...

    Now I do the same for h(x)?

    No, it's from the lesson's practice questions. It gives you the answer but I wanted to do it on my own
